Random Orbital Snader for Mild Restoration Stuff

[ynotme2]

Everyone,


I have a 65 Austin Healey and when I pulled up the carpets this summer noticed I have quite a bit of rust on the floor boards. Mind you no holes. That I know oif yet but no the worse some good rust. So I am thinking about buying a sander and grinding away the rust and repriming the metal, zinc rich primer, and then painting. To stop the cancer in it's tracks. So my question is, what type of sander. I really don't know if I want to buy a air compressor and go that route. I live in a townhome and don't know if the neighbors would like to hear the compressor. Although I don't know if they will like the sander either. But it might be easier for me. So.... do I buy a 4" or a 5" or a 6" sander? If so should I get an random orbit or a regular one. I would like to have the sander for other odd jobs around the house though. Also do I start with 60 grit and then work my way up? Any suggestions or ideas would be greatly appreciated.

Thanks

Tony....

I just finished this very job myself.
Had a fair bit of surface rust under the PO's sound-deadening mats.
I used a steel wire-brush attachement on my regular electric drill. Worked a charm.
Got it down to bare shiny metal, soaked the floor in rust remover ( for no other reason than to make me feel good )
cleaned it all off with break cleaner, zinc primered and painted. Topped it off with under coat.
Not sure about the scientific pros and cons of all this, I'm sure I'll find out in a few years... /ubbthreads/images/graemlins/grin.gif

did you use the wheel style or the cup style?

 

[rulle7]

Both as a matter of fact.
Plus a cone shaped (pointed) attachment that I have no idea what you might call in English. Made of some knife shapening stone type material for a few stubborn spots where the wire wasn't quite enough.
Good luck and happy grinding! /ubbthreads/images/graemlins/hammer.gif

I found some sweet pieces at 3M around a better replacement for the wire disc stuff. Take a look. I am going to buy some in the next week or so and give it a run

I've used these for quite awhile. They work well, but the bristles are about 1/16" in diameter, so don't get into the nooks and crannies the way a wire wheel does.

I would use a 5 inch palm style sander. It should work well. I have a Black and Decker and was astounded at how much better an electric randon orbit sander works than a jitterbug style. Other than very small detail sanders, I won't use the jitterbug again.

I have a 6" electric orbital that I use for body work. unless you're planning on using it a lot,or have several other air tools, I would stay away from air power sanders as they consume large quantities of air and require a fairly large, expensive compressor to keep up. if you sand then start with 80 grit and then go to 120. you shouldn't need to go much finer than that for under the carpet stuff.I also know of some Kick-butt rust stopping primer.If you want, I'll E-mail you about it (in keeping with the "no product plugs" rule)

Ok, I did a private response but I'll put a quick post since I came across it on some other threads here.
POR-15. It's a rust encapsulator/ blocker.It is just like black paint to apply. Applied to cleaned up rust I've never had it come back through, and applied to clean bare metal it's never gonna rust. I've used it on frame and suspension components, rockers and floorpans with excellent results. It is UV sensetive, and if left exposed it will get chalky, but you can paint over it. Also if you do use it, heed the warnings on the can (clean off the lip of the can and wear gloves) this stuff bonds extremely well and does not come your skin off once dry.TRUST ME. check your local auto paint store or search the web under POR-15 to find out about it. Good luck batteling the rust monsters.
