Barrier Coat - Amerlock 400 by Ameron ?

A old marina owner on west coast swears by this product as a barrier coat as it is for industrial use on fishing vessels, water tanks, offshore oil rigs.. etc and a lot cheaper and more effective then Pettit/Interlux etc since its target market is not the West Marine boater. Has anyone else used it for a barrier coat on fiberglass? Im more concerned with performance then $ as Im doing a 50' hull so only want to do barrier coating once in my lifetime on this boat.
Product is owned by PPG. All comments welcomed. Thanks.

My friend uses Ameron on his steel ketch and swears by it. I am considering it when I have my steel cutter redone prior to voyaging. I am also considering Endura, a similar Canadian industrial coating used on buoys, oil rigs, etc.

Thanks Val - but have you ever heard it being used on fiberglass?

My yard is suggesting Amercoat 235. Says they have had good results with it. It rolls on pretty thick, 4-8 mils per coat so only needs two coats as opposed to the 4+ coats for 2000E. The data sheet doesn't include fiberglass in the applied over materials list, but it's epoxy based so I'm thinking that it would be compatiable. Several different people that I've talked to have said that its a good alternative. Nonetheless, I'm gonna contact the manufacturer before using it.

No, I haven't heard of it for fibreglass, but I'm sure the spec sheet for the product in question will cover that off, or a phone call to the rep. If the fibreglass has sufficient "tooth", I don't see a problem, unless it's a chemical one.

If you don't mind another recommendation; you might consider using epoxy. It can be a bit more difficult to work with than paint but it is 100% solids and pretty much impervious to water once you cover to the correct film thickness. Check out the MAS epoxies website for more info. www.masepoxies.com

I have no commercial interest in MAS; you can use other epoxies that are non-blushing.
