I love baltech so Iíd replace balsa with balsa. Quadaxiel is overkill. More for thinner hull
sides or building up transom and chines.
800 gets really good saturation 1200 you need to vacuum bag or get real lucky.
Iíve done a patch in port side about a foot behind the bow. The boat
sank but no water
got in the balsa deck
and the hull
I started my patch with very fine glass on 3 layers. Then heavy weights. Iíve even used .30 and .50 cloth to do minor repairs
The bow has no interior
but even the interior
looks factory gel coat. The boat
skipped along a rock at a pretty good speed. Itís a Donzi 18. The hit tore the lower end of the drive off. Insurance
wrote it off and I dove on it to bring it up. Took two inflation bags we nicknamed the Chrysler bag cause one will pick up a 70í Chrysler wagon.
The bow damage was bad but there were 4 other damaged areas one on the chine I used .50 cloth to fill 1/8Ē damage.
Iíd even suggest using a layer of Matt as a filler on a deck between cloth.
