Transom Repair 23' Outboard

Edloh-

As Fellowship states and as I have done you can gel-coat over epoxy. There are certain prepararions you have to do but it can be done without a hitch.

Gel-coat to epoxy = mechanical bond

Gel-coat to Poly = chemical bond and I think mechanical if the poly is dry?

Get the west sytems book on repairing fiverglass boats it is avail anywhere that sells west systems and has good pointers no matter what type of method and our material you use

as the others have mentioned, with West Systems epoxy, you can definitely put polyester based gel coat on over it.

Keep in mind that when bonding to the existing boat structure, you are only acheiving a secondary bond, and that epoxy is considerably stronger at this, than polyester.

The primary bond (chemical) only occurs when the previous surface being bonded to is not yet fully cured - obviously, all the existing fiberglass structure in your boat is fully cured.

With the epoxy (at least with west systems) after it fully cures - about 4 days, with a good sanding, and an acetone wipe, polyester gel coat will readily adhere.

suggest, as Trayder mentioned, you get the West Systems book - it's cheap, readily available, good info.
