Thankls for all the comments/suggestions. I guess I'll be doing the following:
- Sand down existing bottom cote to smooth edges where bottom coat/anti foul has been scraped down to the gel coat.
- Apply 2x layers of barrier coat to exposed gel coat.
- Apply 2x layers of bottom cao (anti foul) to the entire hull.
This should afford the hull sufficient protection of the season. Then in the fall...SOAD BLAST! Gotta save some money though!
