I recently made my first mould and found out it might have been a bad idea to use rattle can spray paint with this being the result



I want to know if I clean away all the paint with standard thinners am I also effecting the gel coat? A quick rub with a cloth soaked in thinners didn't appear to rub of any gel coat so it seems harmless enough but I'd like to know if this is true or that it does effect the coating?
