Hi all, why not use the same thing you would use if it were a boat - gelcoat.

Available in any color and completely compatible with the fiberglass.

Gelcoat is normally sprayed on but for something that does not require a 
nice finish just brush it on. Gelcoat is thick and one coat will do it.

Hope this helps,

Dale
