If you have cracks and gaps you can use micro balloons or simply add some saw dust to your epoxy. To fill big gaps I would use a quick setting epoxy in that area only , then sand, then apply the sealing coat. With wood you can use epoxy or polyester resins.

I would just sand the paint down as much as possible then just primer. Use an enamel paint, enamel is fuel proof. To protect the finish either coat it with a clear enamel or just lay a coat of epoxy over the paint.

For a two tone. Paint your lightest color first. Allow to cure. Tape off area that you don't want painted with a low tack painters tape. Then spray the other color.

Hope this helps.


Speedmonkey...I have actually made more foam hulls than I have wood. I am in the process of converting my foam designs over to wood so I can produce them faster plus alot of people are wanting kits so they can put together themselves.
