I recently built paint booth and was able to find 22 4 foot paint booth lights from a large truck painting business that closed down. They are commercial lights of good quality with glass 4 foot coverings. They are loaded with overspray and I have been trying to clean the paint from the glass and its very time consuming. I have been spraying on lacquer and using a razor blade but its taking forever. Is there a better product out there for cleaning overspray? Maybe some type of acid that would lift the paint without damaging the glass. I tried searching here but didn't come up with anything. Thanks Paul
