Has anyone seen this problem before. This fall, I attempted to repair
leaking deck though-holes. My Cal 28 uses U shaped bolts for the anchors to
the mast stays (instead of chainplates).
The deck through-holes were 3/8 inch diameter, so I drilled thru the deck
with twice the size diameter holes (3/4 inch). I then taped underneath and
filled in the holes with fiberglass resin. A week later, I inspected the
glassed in holes and discovered some were leaking as badly as before.
The mistakes I made I think were 1) the inside of through-holes were still
wet when I poured the resin, and 2) I used polyester resin and not epoxy
resin.
Anyone have any suggestions what I could do before I head out and re-drill
these.
