Yes in regard to sticking on gel coat. Front of my Komfort was sprayed. Also note the body shops have access to various products. My trailer got damaged in parking accident. After repair they sprayed right over gel coat! My friend still owns my old trailer. Looks new and never loss it's shine after 4 years. We had it done in exact white tint to match Gel Coat. It was about $350.00 to have done. Most likely more now, but they even went over the seems in front cap. Stuff is bullet proof! We even coated the fiberglass propane tank covers!
