Won't hurt the gelcoat Carol. The solvents in Brake Clean are not as strong as lacquer thinner and I have used a ton of both brake clean and lacquer thinner on my trailer and gel coat.
The original Brake Cleaner was tetrachloroethylene (perchloroethylene) commonly known as dry cleaning solvent. The product was banned or restricted for sale
to the public so the newer versions that are now available are usually a non chlorinated substitute.
As with any product test an area before using it. I have definitely seen brake clean melt plastics, pour it in a styrofoam cup and the cup vanishes but no effect on fiberglass or gel coat.
