That epoxy is a great barrier coat.
If you applied it before fairing the hull you just cost yourself extra bucks, and used more epoxy,aka, interprotect to reseal it.
105 epoxy can be beefed up to add abrasion resistance with graphite power and water incursion protection with powered aluminum.
West systems offers these products.
Once applied you Scuff it up with 80 grit before bottom painting.

It's done, I did 105 then thickened 105, then sanded, then barrier coated with interprotect.

Interprotect is epoxy with additives, correct?

West systems uses epoxy and additives to achieve the same protective barrier. Graphite powder for abrasion resistance and aluminum powder for water incursion protection.
I don't understand why you'd do both.
Why add more epoxy to achieve the same result.
The only difference I note is the ability to re coat with more Interprotect without sanding between coats, and no sanding for Bottom paint.
But if you coat with the west systems its can all be done in succession, so no sanding in between.
You just have to keep the epoxy from kicking too quickly.

Perhaps it's the decade or so I spent doing barrier jobs just as you describe, with a fair failure rate, on several hundred bottoms? Could be.


2000 is simply a superior moisture barrier. Advantages also include recoating with a six month bond window, and the big one, you can chemical bond the AF to the barrier this way. You can't with neat resin, due to amine blush and a very short bond window.

Thanks for that great tip Minaret.
Kudos
