powder coat up-date

did some powder coating last night of the steering arms and one of the spindles. what a nice look. the paint came out super glossy and hard as ever. i really like the final product. this was one of the things i was concerned about as far as rattle cans. i know there are some out there that swear by rattle cans and i will be using them as well on some parts, but powder coating to me is the way to go. i will be posting some pics on my website very soon.
 
Re: powder coat up-date

for me it's a stark difference from spray. you have to think a little more before applying so you don't paint what you don't want and the prep work is a little more involved, but i probably would prep just as much with rattle cans. anyway, i'm sold on it. the mess and fumes were minimal as well. i like that in one hour the part is done and ready to be used.
 
Re: powder coat up-date

Sounds like it just might be the way to go. Keep us informed please.
 
Re: powder coat up-date

jack, it's piece by piece now but the results are great. i had some other things to do this weekend, but later this week i will post some before and after shots.
 
Re: powder coat up-date

Hmmm, hate the thought of takeing Miss Agatha all apart again to powder coat.
 
Re: powder coat up-date

I think I have powder coated every part on the 58 I am doing.
That is as long as it fits in the oven.
All the suspension, calipers, and evrtything under the bonnet.
Even some parts that will be car color are powdercoated off white before the OE white goes on.
Body clips, wire clamps, and a whole lot of nuts and bolts too.
 
Re: powder coat up-date

/ubbthreads/images/graemlins/iagree.gifi'm finding that i want to powder coat anything i can fit in the oven as well. as you said jack, i don't really want to take apart assemblies i have already painted, but from here on out i will consider any and all remaining parts.
.
spritenut, do you remember how you powdercoated the calipers? specifically, how did you cover the piston area to prevent paint from getting in the piston chamber(s)?
 
Re: powder coat up-date

I have a question about powdercoat...How is it affected by brake fluid? One area I have always had a problem with has been the master cylinder and pedal housing piece. No matter how hard one tries, fluid gets on the paint and then krinkle-city! Would powder-coat be the answer?
 
Re: powder coat up-date

Maybe someone we know will do a test or has done a test?
 
Re: powder coat up-date

Silicon (aka DOT 5) brake fluid may be the way to go. It doesn't rot parts or paint as I understand it. Also, won't absorb water.
 
Re: powder coat up-date

My newly delivered brake master cylinder from Apple Hydraulics came with a warning against using silicon fluid. Don't know why - perhaps someone can chime in
 
Re: powder coat up-date

I have been using silicon fluid for 10 years now.
No problems braking and no messed up paint.
And I do believe the seals last longer too.
 
Re: powder coat up-date

powder coating is supposed to provide better resistance to chemicals but brake fluid i'm not sure of. perhaps i will set up a test.
 
Re: powder coat up-date

Oh boy another thing to find that is not available localy. Maybe my favorate place can order it.

I saw this firsthand so I can commnet on this. I have a friend Roger Mandeville, he's a ex IMSA GTU Champion, he has a race prep shop. He had a customer's RX7 race car there, the entire tub had been powder coated. This car had been stored in it's enclosed trailer for close to a year, when Roger got this car out for prep for a race, the master cylinders had dumped their contents on the drivers floor board which was powder coated and probably had been like this for months, they just wiped up the brake fluid and the powder coat was not affected in any way.
 
Re: powder coat up-date

Ohhh, now that's a testament.
 
Re: powder coat up-date

I got my last master cylinder from Apple also, and noticed that warning. According to them, the the type of rubber used for the seals would not last! Could that be fixed by using seals with a different compound and are those be available? Anyone out there know? And if so, would all rubber in the hydraulics have to be replaced (wheel cyl.s etc.)?
 
Re: powder coat up-date

Knowing how Apple does shocks, they probably use seals made from old styrofoam coffee cups and they won't hold up to anything.
If switching to silicon, all the seals need to be NEW and the hoses and pipes flushed with alcohol.
I don't do this unless I replace the entire brake system.
And when I do a brake job on a 40 year old car, everything is new.
 
Re: powder coat up-date

Uh-oh! Another "satisfied" Apple customer?
