Hello,
I am still relatively new here, and I have done a lot of searching online and on this forum, but I am still wondering about one thing.
I am about to tackle replacing some rotten core in my transom. My 1988 H26.5 has a small outboard motor mount and there must've been water getting in through the mounting bolts. I have bought and read the West System book on fiberglass repairs and have all the materials in hand, but I'm not sure about one thing.
The repair will be done from the inside of the lazarette. It is a great place to do my first FG repair, as it doesn't have to look pretty. The inside of the lazarette is just fiberglass that looks to be painted. Especially the woven roving in the one corner. I seem to recall reading/hearing that you can't epoxy over polyester paint. Is this polyester paint, or is it epoxy paint, or is it just tinted epoxy? Do I need to sand off the "paint" in the areas that I will be laying up new fiberglass for the core replacement? Do I need to totally remove the paint, or just rough it up?
What kind of surface prep do I need to do to the areas that I will be epoxying onto? Any help would be greatly appreciated.
Thanks,
Ryan
