View Full Version : Miata seat prep continues

01-24-2010, 12:47 PM
Now that the trim is in, I decided to keep following BobbyD's path to do these right.

This morning was a good time to get rid of the Hog Rings the easy way and get the seat cushion pans ready for paint with some POR15 Rust Remover.

A few applications of this stuff, a few hits with a Scotch Brite Pad and brass brush and we're ready for paint as soon as the cracks and crevices dry.

These bad boys get rid of the Hog Rings in about two seconds each, with no effort at all.


A few before shots. This is the passenger seat. The drivers was worse, but no rust through, just surface coated.


Much better to cut the rings, move the seat cushions back and get all of the sides done as well.


Be smart if you ever use this chemical and wear gloves and eye protection. Oh yeah, ventilation helps too. It is acid based and smells a lot like Dupont Metal Prep we used in the 60-70's at the dealership. That stuff was green at the time. I should remember it, because I hated it and the smell that it left on your hands and what it did to your skin before we were smart enough to protect ourselves.


First coat on and ready for Scotch Brite.


After two coats, Scotch Brites, small wood handle brass brush once over the cracks and a soap and water wash down.



Now for some drying time and the paint will go on later today.

The Miata seats are nice...I have them in my '92. :laugh:

01-24-2010, 12:58 PM
Paul - that is excellent. Thanks for the illustrated step-by-step. That Metal Ready looks like powerful stuff.


01-24-2010, 01:17 PM
Don't follow that Paul. Why not remove all of it ?
I thought you where gonna have them redone anyway.

01-24-2010, 03:20 PM

I'm lazy for one and the tops of the trays are all shiny with no rust. Secondly, the upholsterer said to leave everything as until I bring them in. He will clean and lube the tilt mechanisms when he replaces the covers.

Once I get them back, I'll re-tap the junk out of the threads and put the tracks back on.

01-24-2010, 03:44 PM
OK Doke

01-24-2010, 07:58 PM
I'm eager to see how this comes together Paul.

01-24-2010, 08:40 PM
I am too, Tom.

I'm still undecided about putting the roll and pleat pattern down the middle of the seat back and cushion as a throwback to the TR6. Part of me says yes, the other part says why bother, go modern. I'll probably flip a coin the day that I take them in.

This picture of the pans with the second coat of Rustoleum applied. That will do it until they come back from the shop.

Seat tracks are all cleaned and degreased and straightened to fit the adapter kit. Now I have to cut off the studs and grind down a few ridges and paint those guys. Then a re-lube of the rollers and tracks and they'll be ready.

01-24-2010, 10:31 PM
Looking good Paul

01-25-2010, 12:08 PM
Seats are at the shop as we speak. Material for headrests going out for perforation.

We checked the speakers and they've been hacked, so out they'll go. I just ordered a new set of upgraded Millenium's like BobbyD used in his.

The original padding is very good, but he will be supplementing it with additional foam.

I am going with the roll and pleat design in the center back and cushion.

01-25-2010, 12:13 PM
You're rolling now Paul - when do you think they'll be finished with them? I'm antsy to see them (in a good way) and they're not even my seats!

01-25-2010, 02:24 PM
I called the shop to tell him that I have some new speakers coming and he told me that the perforated material will be back next week. I'll have the speakers late this week, so things are looking a lot better than a week and a half ago when I didn't even have seats.

I'll be picking up the tracks for the body shop tonight.

01-25-2010, 06:30 PM
Picked up tracks and they are just about ready for paint. Two key things that you need to do, which I confirmed with Bob. All four (4) of the ends need to have the raised portion ground down to allow a flush fit with the adapter rails and the stud should stay above the surface of the track. The stud also is a big rivet which if cut flush with the track, might weaken and come loose. Staying just above allows it to hold the front section securely on the track itself.




01-25-2010, 07:06 PM
Paul- You got a before and after of those tracks,the grinding

01-26-2010, 01:56 PM
Sure do Don. I'll post them tonight when I get home. You can see it in these, but not that clearly. I think that I have better pics at home.

01-26-2010, 05:22 PM
Hey Paul why dont you put the seat covers on yourself? I did mine a few years ago. I searched the web and found a great detailed article on how to do it and purchased leather seat covers from Katskins, it was really easy I bet you could do it


01-26-2010, 06:12 PM
I could have pulled them off easily, but there was no need. I did lift the seat cushions and foam completely off the pans to check them up top. The upper pans were rust free and shiny. The shop will be using the covers to make patterns to cut the new seat covers, so he prefers to do it himself and do the disassembly there.

I will go over with the speakers and wires when he is ready and install them and test them before it's all buttoned up.

Speakers came today. I didn't know the company was in Mass, not that far from me.

01-27-2010, 08:59 AM
if the head rest are the only speakers you have in the car then you can hear them, but if you have additional speakers behind the seats, the head rest speakers are useless, at least thats what I found out and with the top down, might be different with the top up


01-27-2010, 05:21 PM

BobbyD claims that with these new Millenium speakers (he recommended them) that he is eliminating his speakers behind the seats because these sound so well with the top down and on the highway. I still have my front speakers and will be using them as well.

01-28-2010, 02:13 PM
Any more updates or pics Paul?

01-28-2010, 07:05 PM
Tonight. I just got back from working in CT all day. After dinner pics of the new speakers, ala' BobbyD and a different twist on a wiring harness that I'm going to make. Actually, following Bobby's lead a bit, but I'm using a different type wire to make it easy to tell which speaker is which.

Got a lecture from Alan at A&E yesterday about not painting the tracks yet. That will have to wait till the weekend. He was in my workshop when he came to take my hardtop to the body shop to start the prep for painting.

A little seat update.

Once again, I would not have been a pioneer on this project, so I want to thank Bob Danielson for his hard work and documentation that led me down this path. Once all the bills come in, I may not feel that way, but for now, I'm happy and grateful that he did all of the leg work which made getting what I needed a lot easier.

And to make my darling wife a little happier, I wen a step further by ordering a heated seat package to go along with everything else. Yeah, the WIIT syndrome took over, once again and I decided that this was the best time to do the heating elements. Now maybe she'll be happier when I make ride over to the Cape early in the morning or we go for those late night spins and I don't want to put the top up.

So here are the speakers, a dummy proof wire harness with four (4) different color wires for each seat and a picture of the heated seat pads. Although I ordered the premium step up with three temp settings. This is the link for the heaters: Check Seat Heaters (https://www.gomiata.com/gomseatheat.html)

I'm going to use the two headlamp relay circuits in the new Classic Fuse Panel kit to install these, and leave my existing four relay setup in place.

Will be sending my seats to you for retro fit when I get there.
What's your service rate?

01-29-2010, 04:09 PM

My rate is cheap. It's the parts that go into these little projects that keep adding up.

01-30-2010, 11:26 AM
I just updated my website with this and several other projects that include more pictures.

I've posted a bunch of updated photos to my web site for this weekends work to the seat page.

Great write up so far Paul.

02-05-2010, 02:20 PM
Additional seat updates as of this week.


Dorman part numbers are 84546 for the .187" Female & 84547 for the .110" Female connectors.


This is a pictures of the seat foam with one of the original speakers and the original Miata wiring.


The speaker box will go in the spot on the left and new speakers will replace these OEM units.


The wiring then goes through the center hole above the top of the radius in the center panel recess and out the back.

That is where the "V" is shown with blue wires coming out and then the wires follow a path that is cut out down the back of the seat.

Just a shot of the bottom cushion and that is the way it was when uncovered.


And from this pile of patterns a set if new covers will emerge. Now all I need is the seat heaters.

It may not look so great on this table, but it will when Eddie gets them completed.


02-05-2010, 05:01 PM
The seats are going to be great Paul, love the color.

02-05-2010, 06:03 PM
Thanks Tom. I think that they will look great too.

02-05-2010, 06:25 PM
I love mine, although they're not as pretty.

02-05-2010, 06:57 PM
If I had black interior, the seats probably would have gone in, as is. This is another project taken to the max, but my primary reason for getting them is comfort, easier sliding, adjustability and the better head restraints.

02-05-2010, 08:07 PM
...comfort, easier sliding, adjustability and the better head restraints. Yes, yes, yes and yes.

02-06-2010, 09:07 PM
Paul...We are interested in the "Hot Seat" idea. Any idea
how much juice these might pull? Gil

02-06-2010, 09:24 PM

I will get the exact, but I think that it's 3-5 amps per seat, or is that per set?

This is the link to the site that makes them. I actually bought mine from gomiata.com

Check Corp Seat Heaters (https://www.checkcorp.com/seat-heater/seat-heaters.asp)

02-06-2010, 09:40 PM
Thank you Paul...Will have to keep this in mind as we progress. Gil

02-07-2010, 09:26 AM
I put seat heaters in my 3A seats when I re-did them. They comefused for 10amps per side. Mine are the two position heaters, Paul's are 3 position but that might mean that the total heat is the same, just 3 positions instead of 2. You'll need an alternator for this upgrade as the generator probably won't be able to keep up.

My heaters are the same as Moss but purchased elsewhere (for less). There are a couple of heater install photos here: https://home.myfairpoint.net/kentech0822/triumph/tr3seats/

02-12-2010, 12:35 PM
Lunch time update. Seat heaters arrived and progress in upholstery shop.

Another package arrived today.....more progress.


This is the entire package. Switches on the left, heaters in the middle and modules on the right.


If you look closely, you can see the grids in there.


Controller and wiring for one seat.


These two connect the seat back and seat cushion together and into the main harness.


This will be the general idea but with the harness lower and out the bottom.


This one goes on the seat cushion.


The other seat patterns taking shape. These will have the backing stitched in place then trimmed and ready to be fit together.


Just the plain backs of the seats, less backing.


This is one set of seat patterns cut and trimmed with the backing on. I know Bobby is checking this out.


02-12-2010, 12:59 PM
Heated seats are sooooo nice to have! Thanks for the update Paul.

02-12-2010, 05:19 PM
Heated seats with real headrests and lumbar supports and tracks that actually glide easily.......

02-12-2010, 05:34 PM
Paul- How often do you move your seats?

02-12-2010, 06:09 PM
When my wife wants to drive or my little nephews ride in the car. I just hate things that are hard to operate and my wife always has trouble moving the TR seats (she always did), even with new track assemblies. They were no better than the original ones.

Remember Don, "a happy wife, is a happy life".......

02-12-2010, 08:01 PM
Oh, that's right. Used to be her car.

02-12-2010, 08:29 PM
Used to be Don, used to be.....

Ouch, ouch...I was only kidding honey, honest..............

02-12-2010, 08:38 PM
Nice :laugh:

02-15-2010, 03:46 PM
So now I know what Bobby D meant about the "pleating foam."

I delivered the speaker wiring harnesses and the speaker boxes and new speakers. Eddie will finish the pleated sections today and begin sewing everything together and start test fitting the covers by the weekend.


These pleats are only half done according to Eddie. They need to be sewn again from the opposite side.



02-15-2010, 05:12 PM
Looks very "period" Paul.

02-15-2010, 08:33 PM

Same size as the stock TR6 pleat that is molded into the seat. That's my link to the past in these seats. No, it was not completely my idea. I was thinking about it, then I saw a blue interior on BobbyD's site that showed these pleats and I wanted to do it too.

02-15-2010, 08:39 PM
Makes me want to eat a chocolate. mmmmmm
