Removing Old Urethane From Paint

Hey, anyone know any tricks to getting old urethane off of paint? We installed a windshield and the previous installer glued the moldings down to the paint job. It looks like it's been there a few years. Late !980's model car.  Dave 1/9/01

I use plastic razor blades, or the equivalent is the flat end of a glass man's fiber stick - some of the sticks have a beveled flat end that is sharpened. I wet the surface with glass cleaner while doing this.  Glassman John

I put urethane cleaner on the dried urethane. It softens a little and I take either a pre made chisel end plastic stick or I put a round end one on a grinder and carefully scrape most of the clump from the paint. I then put more urethane cleaner on it and let it sit and it will soften up enough to be scrubbed clean with a paper towel.  Steve

Try loctite primer on a cloth. A lot of times it will take the urethane and also primer off of paint, works on cloth also. I have used this a few times. Another thing you can do if a car has bad paint and you can not clean it try using wax it cleans a lot off adhesive that sometimes we have a tendency to get on vehicle that have not been waxed to often or light colored cars always. I keep it in my van for those OOPPSS!!!  Rick L
