acetone

[77c15]

I went through 4 (four) cans of acetone to remove the top color off my truck. Now, i'm trying my hardest to scrape the bubbled paint off without messing up the light blue original paint underneath. Is using a progressive sandpapering technique a good idea (coarse grit, then medium, and finally fine)? I'm trying to keep the factory color as much in tact as possible so the guy or gal at the paint shop can match it up pretty decently. The interior is luckily untouched by the crappy-painters hand (previous owner). Let me know what you guys think! THANKS!!!

Just my opinion but I would take a DA with some 80 grit then 180 to it and maybe even step up to 320 for a final sand. I have taken poor paint jobs off before with a razor scraper. then you only have to sand the original paint and maybe hand sand in the tight areas or body lines. If you are going to have it painted I wouldn't waste allot of time trying to save the old color. The old paint would still be there and the shop or yourself could do a urethane primer coat and then you could wet sand that. They should be able to match it with the paint code or the door jambs. Sounds like a allot of time and elbow grease to me.

Thanks for the input, "Blazin"! I used as much asetone as possible to get the red and white off, but it was having no effect at all on the factory paint, so I roughed it up a bit with some 180 grit and then did a rattle can primer job with rust inhibitor. I'm going to wait until I get the new fenders, cowl hood, and bed before doing anymore body work to the old gal. Thanks again for responding, though!
