I painted my oldie fibreglass boat with Jotun 2pac to make it look nice again. The prep is time consuming but if you have a good air compressor you can do it much easier - the sanding and spray painting. I sanded, my mates did the spray. I think it was about $500 for the paint and thinners etc. Looks much better now but even 2 pac paint is not as tough as gelcoat.Attachment 80089
