paint removal questions
well i did a search but there wasn't much info in the threads that came up. i was planning to buy a large soda blaster to strip my cars and use it to make money stripping cars and whatever else people would want blasted.
well today i stumbled onto some threads on other forums that made me think soda blasting is a bad idea. they were all talking about how hard it is to get paint to stick after being soda blasted. i've never seen anyone's project update thread mention soda blasting. anyone have any input on that?
what methods do you guys use? with soda blasting no longer a good option i'm left with sanding or chemical stripper. i've used the chemical stuff before and it worked great, but that was back in high school and i sold the car before i ever painted it so i don't know if there would've been some future problems. i know you have to be careful to keep it out of places where it could seep out later, but how do you clean it off or "neutralize" it after stripping? does anyone know? that was asked in the threads that came up in my search but no one ever answered that question.
a couple of the build threads on here looked like the paint was just sanded off with a 90* die grinder. can those of you who just sand it off tell me what you use and why? i'm concerned with removing too much metal or warping it. thanks

Greetings TRaven!
The concern I've had with soda blasting a car for paint removal is that the powder settles into every nook and cranny of a car body shell and is very difficult to remove - the same with sand or media blasting. Just when you think you've got the stuff completely removed by vacuuming and air blowing, then you're start priming, the powder/media/sand blows out of some crack/crevice to contaminate the surface. Then you've got to address the issue!
I prefer to chemical strip using Klean Strip Aircraft Paint Stripper. There are quite a few other strippers on the market - this is the product the shops I've worked at over the years used because it works. I've tried the "organic" stuff but really didn't work very well. It took too many applications and still hadn't removed very much paint.
I can only suggest that you talk to your local paint supplier and see what they carry, pick up the product sheet and read all the info. Do research on the 'net and stop by some body shops and inquire what they use to strip paint.
Other alternatives are "3M clean and strip discs as well as coarse bristle discs".
Good luck with your project - hope this helps!

10-25-2008 #4thanks Alchemist, everything i read in the past about soda blasting made it sound like it was easier to remove soda, than it would be to remove sand after blasting. but recently i've been reading that its probably the most difficult to remove of all the blasting media. the other thing i was reading is that even after trying to remove the residue left by the soda people were still having problems with paint adhesion.
i guess i'll go with a combination of aircraft stripper and sanding but i'm still not sure how to remove and residue left by the stripper. I'm sure there are instructions on the can but i'd rather hear what the people who use the stuff have to say about how to prep the metal.Traven
