paint drip removal
Hey folks:
'87 3.2 Guards Red. Paint is lovely, but there is a drip on the front bumper where apparently a P.O. was walking past with some Guards Red touch up for elsewhere and dripped on the bumper. It's quite proud of the surface and ran down the front of the bumper. How would I get it off? I'll try to post a pic. Sheldon ![]() |

Advise as to depth of experience with power buffers and the like. Micro wet sanding and polishing will always work but a little bit of time under your belt will save you grief.
Original paint? Options increase as you can moderately use solvents to cut the miscreant's slop without jacking with the base paint. 21 Line is very tough but you have to be scared.

Yeah, no significant experience with power buffing. Do that stuff by hand.
As for original paint, yes, but. Does one ever really know that no area has been tampered with? Its a bumper after all. If it's not original, it's a damn good and thorough replication of the original. Mask, sand? |

Most touch up is lacquer based and can be removed with lacquer thinner. Test on a door jamb or under hood area to see if the original reacts with thinners.

This just happened to me, single drop of touch up paint on newly painted fender. Local shop gave me a small bottle of Glasurit Reducer and it worked like a charm! Touch up paint doesn't have hardener, so it came right off. Better to remove the drip ASAP though...

Lacquer thinner will remove non-catalyzed paint, but it can dull the surrounding paint. Reducer works really well with no side effects.

you may be able to wet sand it with 600 and a small block, then buff it back to a shine.
problem is how much old paint is still on there and how far down will you have to sand to get all the color off. if it really bothers you i would try something like a popsickle stick with 600 and start by sanding just the drip. sand lightly. make sur the stick id flat.

lets approach this with a solvent before sanding. There is a good chance it will come right off without removing any of the original paint. A small can of reducer will run you $15 at the auto parts store

One of our paintless dent guys, who also does paintwork, would probably slice it even with a razor blade. But I know my hands are not steady enough to do that.

I'd recommend isolating the drip with tape to protect the surrounding paint. Use more layers of tape to keep the adhesive from reacting with the reducer. Work slowly to limit work against the good paint under and around.
