Comex Paint Compatiblity

[ChrisAv]

Hello.
Is Comex compatible with Blue Water (precisely Blue Water - Antif.P.PRO COAT #67 Hard W/ SR Blue) which I understand is a version Pettit Trinidad SR?
Also, Is Comex an epoxy based paint?

Thanks.

So I found the answers all by myself!
I'm posting them for whomever may be interested;

Comex has nothing to do with Pettit.
Comex refers to a bottom paint from Amercoat. That is the same as ABC3 from Ameron. It’s just a different distributor.
Comex (ABC3) is an ablative paint whereas Pettit Trinidad is a modified epoxy paint.
Ablative type paints can be used over modified epoxy paints.
Modified epoxy type paints cannot be used on top of ablative paint unless you completely strip off the old plaint. If you don’t remove the old paint, the modified epoxy paint will not adhere properly.

One more thing;

Blue Water Pro Coat #67 Hard w/ SR Blue (that’s what was described by Baja Naval, the yard that performed my last paint job in Mexico) is a modified Epoxy bottom paint. On the Blue Water website, it corresponds to Copper Pro SCX 67 HARD Royal Blue

People are more familiar with the other Pro coat 67 which are mostly ablatives.

Not even close to true.

Actually, it IS pretty close to true!
You extracted your excerpt from the Pettit website. What you have OMITTED to include is the introduction paragraph on paint type compatibility. And this is what it says: "There is an old rule of thumb that says an ablative paint can go over a hard modified epoxy paint, but a hard modified epoxy paint should never be applied over an ablative. While this holds true most of the time, there are some exceptions."
I'd like to point the readers' attention to "... this holds true most of the time...."
That's prettry close to true in my books. I think in the books of many readers as well I will trust.
