I was using LusterKote spray primmer to prepare an engine area for painting. I now have overspray all the way to the tail. You mostly feel it, but can also see it in a few spots. I don't want to make a big mess trying to remove it. Any Ideas? Thanks.

One of my planes received some acrylic sealer overspray on it when our house was being built. I was able to get most of it off by using a mild bathroom abrasive cleaner. You might try whitening toothpaste or something slightly abrasive. Anything overly abrasive will dull the finish. It is a tough problem you have as I have painted monokote often and the paint really likes to stick.

Clean it off with a rag dampened with acetone or lacquer thinner. It will wipe right off and the solvents wont hert the covering unless you you go over a seam too much.

Acetone will do it.

Will acetone change the color of the covering?

I would first try alcohol, then if that doesn't work, go on to more aggressive methods.

As far as affecting the Monokote, the color is in the adhesive, so cleaning the surface will not harm anything.

Been using acetone to clean M/K for many years. I don't mess with anything else.

The acetone worked! Not only did it do the job , but was very easy, very little rubbing at all. Just got the soft rag wet with acetone and wiped the covering as if I was cleaning it. Thanks everyone for your help.

Ditto !

Acetone.

This might sound weird but sometimes a bit of soft brown masking paper screwed up in a ball will remove it easily.

This may sound weird but a bit of masking would prevent the problem in the first place. Spraying without protecting the surrounding surfaces is not a good idea. The overspray has to go somewhere. It usually finds it's way to unprotected areas on our airframes.

Aerosol cans are much worse than spray equipment, too.

I recently painted three airframes within a month. Two were using HVLP spray equipment. One was an aerosol. The aerosol supplied 5 times the overspray, as the other two paint jobs, combined.

Tom i'm sorry i must have left a few things out.As a lifelong professional spraypainter i thought that saying you should mask something off would be too obvious.

I didn't mean to single you out. Sorry. I meant it as a play on words.

I thought masking, beforehand, was obvious, too.

Since the OP didn't do it, I guess that it wasn't.
