opinions on paint removal

I need some good opinions on how to strip down my camaro im not ready to do final body work and paint but im ready to install the engine and transmission and i need to paint firewall , engine bay, under body exc and i was pricing having it blasted and thought i could have the whole car blasted. around $500 to have it sand blasted or $1800 to have it soda blasted. 4 different places say they can sandblast it with out warping the sheet metal but the guy with the soda blaster say sand will destroy the car. I know sand will scar metal but how risky is it,could i have it sandblasted and leave the larger panels and just do the door jams, around windows, firewall, under body exc and i could sand the doors,roof,hood,quarters stuff like that or would it warp everything

Chances are that if your painting the engine compartment and that it's factory paint and the fact that it's been covered (with your hood) it's in respectable shape, Clean it, scuff it (grit or whatever abrassive you use is dependent on what type of paint your going to put over top of it) and paint it. If you plan on stripping the exterior of your car you can sandblast. Be sure you get somebody that knows how to sandblast body panels without warping them. Soda blasting is less likely to damage or warp your panels but it will cost more. You can save money if you sand the car down using 80 grit on a DA. This is going to take a whole bunch of time and is messy. Another option is to chemically strip the car with paint stripper, (even more messy but does the job). You could have the jambs and areas like that blasted and doe the rest with 80 grit or stripper but it's all a matter of preference. I prefer the 80 git method because as I'm stripping I can see what I've got underneath from panel to panel. Like I say, it is a matter of preference.

If you do strip the entire car be sure to use an epoxy primer over the bare metal shortly after stripping to ensure rust doesn't become another problem.

I was going to post a reply, but 69Widetrack said what I was going to say. So, I'll merely second his motion.

Most of the time, underhood stuff can just be thoroughly cleaned/degreased and scuffed for paint. You may have a few areas you need to wire wheel and spot prime. A rust preventative primer would be good on those areas.

Its really hard to give alot of advice because I cant see the condition of your car or really know how carried away you want to get on the restoration. I think alot of people sandblast parts that could easily just be cleaned and repainted just for the sake of sandblasting.

Existing paint thats in good condition and not flaking is the best base there is IMHO.

I also agree with everything widetrack had to say

sand everywhere

I had my model A pickup bed sandblasted and then I blew with and air hose, washed it, blew it again, I primed it then when I sprayed the color I got sand out of the cracks and into the top coat, If I do ever get around to the project pickup behing the barn I will get seam sealer to keep any sand from coming out again on the next one. I had the 29 nash roadster stripped down to seperate body panels and the guy knew what he was doing to sand blast it. I made New upper back and lower back panels and welded it all back together, replacing the old wood with steel tubing,

Andy's right, your good to go...still make sure that the guy behind the sand blaster knows what he's doing.

I'd ask whom ever you are gonig to have sand blast the parts/car.. put in writing , that any panel they warp, they'll replace..
and My guess is you'll never find that,
go buy a good da and have at it..
good luck

I think he just wants to blast the PITA areas... he was going to DA the body panels, far as I could tell

Hell, IDK, I'm confused at this point!! LOL
