Stone Guard Finish
 

I have an 87 RX7 that I am getting ready to paint. Does anyone know if the stone guard finish on the bottom of the car is a painted on finish or a plastic film. It sure doesn't sand very well. What is the best way to remove it ?

It's a special type of coating...
Use a chemical paint stripper to get it off.

That's what I was afraid of. It really doesn't look bad but I had some rust in the lower quarter panels that I had to repair. The finish no longer matches and I don't know how I could possibly duplicate the factory rippled finish.

I think it involves polyurethane. Anybody?

We tried several auto body "experts", and bottom line was there is now way to replicated it to match the stock texture - you'd need to strip the whole thing off and reshoot with something else.&nbsp We just end up stripping the damn thing and painting it smooth on all the FC full paint jobs we do... :)

what chemical will touch it? I ended up grinding that shit off, many many days with a DA sander and 80 grit...

I dunno man, I wasn't in charge of finding all the chemicals. :)
It was some type of aircraft paint stripper - pretty nasty stuff!

Well, never tried chemicals, hell, just regular paint stripper might have worked.. Anyway, if you DO decide to strip it by grinding, you're in for a work out, and a LOT of sanding discs. That stuff is tough!

Yes tough is correct. It's like trying to sand a Rock. If I can't figure out a way to duplicate it in the repaired areas it looks like I have a lot of work ahead.
Thanks to all for your advice.

just go to a local parts store and buy the aerosol can of aircraft quality paint stripper, Get some plastic to go under the edge of the car and Some sort of paint scraper to remove it. I used a plastic bondo scraper. It took about an hour to remove it all.

Yea, I'll give it a try. Hope I don't get too carried away and do the whole darn car !!

that would work, If you wanna, Just get the gallon size, IT works on jerk neibors to, Ha ha
