I'm restoring a wreck of a boat, my first project. It is a 21' Romany
Fisherman from Engand, circa 1960's, powered by a 4-107 Perkins
diesel. The boat has a certain Tonka toy look to it, like a caricature
of a larger tug-like boat. Anyway, I have lots of questions but I will
pose only a few at a time.The gelcoat on the bottom was like dried
mud- all cracked and pitted so I ground it all off up to the top of
the boot stripe. I then epoxyed a layer of cloth with 4-5 coats of
epoxy, sanding and fairing, between each coat. Then 4-5 coats of
sprayed Interlux 2000e, sanding and fairing between coats. I'm waited
till later to bottom paint it. The upper hull was painted over the gel
coat, this I sanded off.
1- Should I grind out every crack, starbust inpact fracture and flaw
in the gelcoat on the hull, Then repair with epoxy putty? Sand,then
spray with epoxy primer before I paint?
2-Can I sand the decks, wheelhouse etc. Epoxy prime, sand, and then
paint? There are a million small fracture cracks everywhere, will the
epoxy primer repair these?
