Paint removal

Trying to get down to bare metal on the inside of a 35 year old tailgate with original GM primer and paint. Was able to do the high spots with power sanders, but can't get into the corners and low spots, even with a 3" disc on an angle grinder.

Tried some paint remover, but I think it was better suited for home paints and varnishes.

Any ideas?

Neither link works for me, why don't you just post them to the group instead of a third party link?
A sandblaster sounds too easy, is there a problem with that?

OTC stuff at hardware store isn't going to work. You need aircraft stripper - it's nasty stuff. Goggles, long pants and shirt, air filtration and gloves are the minimal. Washes up and neutralizes with water. Best to spread newspapers under the area being worked on and use 3m pads, scrapers to remove the bubbled up paint.

Thanks for the responses. I had read about aircraft stripper, but didn't know if it was hype or actually more aggressive than what I used. I'll give it a try. Bead blasting would be ideal, but I thought it would be too expensive. I'll see I can get it done locally without breaking the bank.

As for the links to my Google Photos account, I don't understand why they don't work, because I link to photos in that account all the time on other forums. When I click on the links they work fine, but that's probably because I'm logged on to the account. Anyway, what do you mean by "post them to the group"?

And I wonder why the "insert image" tool doesn't work on this forum?

Yes, it was no problem.


Also, if you decide on the aircraft stripper - it sometimes can take several coats to take off the paint. I stripped a '66 Chevelle that had 7 paint jobs on it, somewhere around the 4th layer down I ran into an Imron paint job and that took almost an entire gallon of the stuff by itself.

OK, I found a company in Dallas (around 30 miles south of my place) that quoted me $60 to media blast the entire tailgate. Dropped it off Friday.

Can't believe I didn't look into it sooner. Guess I was thinking it would be much more expensive. In fact, the first place I called quoted me $135-$150, but they wanted to see it first. And they kinda acted like it was a big job and might cost even more, whereas the place I chose does entire car and truck bodies.

Will get some aircraft stripper because I forgot to drop off the hinge and latch parts. At least I can drop those in a small container and let them soak.

Thanks for the ideas, guys!

Permatex spray gasket remover is aerosol stripper. If you spray it then place a piece of plastic sheet over it, this will drive the acid vapors down into paint.


Careful when blasting, can cause heat warpage if done too aggressively. You might want to try dry ice blasting, if available.

Great job for $60! Thought there was a lot more rust, but this is it! Surface rust around seam sealer made it look worse than it was.

Sunlight must be playing with me here, because the metal color is light grey.
