Re: OK, so I'm Sanding My Bottom...
Just finished up sanding... Feels like I've been sanding for a week...
Wait a second...I have been sanding for a week...
Plan is to fill and fair with Fiberglass Marine Filler and then a coat of Polyester Resin overall, scuff sand and then hard biocide finish...
Can you remove that sea strainer and lightly sand that area too? I took mine off this year allowing me to paint under the strainer but I had to take out the 4 screws holding it in place.
The 3M Marine Filler is a vinyl-ester product but seems to be intended for what you plan on using it for.
Conventional wisdom has it that epoxy resins have better adhesion than polyester resin which is why people barrier coat with epoxy. However, David Pascoe doesn't seem to think that conventional wisdom knows very much about blister repair.
Your hull does not look so bad after your sanding so have at the next phase.
Good luck with your plan.
