The best epoxy paint?

[AcroSteve]

I see the epoxy paint that Aquatic Ecosystems sells is pretty popular with the plywood tank builders.

Is that one of the better ones available, or is the availability of it make it attractive?

The thing that I do not like about it is this

(after long exposure to UV, it typically develops a chalky surface).

.

I am looking for a dark blue or black epoxy paint that will stand up with out this problem.

I found this, but know nothing about it and sadly, it appears to be only available in a 2 gallon kit size.
It is called PoolCoat. For about $220

I believe the Sweetwater Epoxy Paints are so popular because they are specifically designed for aquaculture and are proven to be safe for use in the aquarium setting.

Tap Plastics sells a nice marine-grade epoxy resin that works nicely, but it's very expensive. I've seen people use all sorts of things to seal their plywood tanks.

There are hundreds of products you can use including Bondo All-purpose Fiberglass Resin, 1-part Garage Floor Epoxy Paint, and a number of different 2-part epoxy products designed for the boat industry. I'm planning to build a plywood tank soon and will be using fiberglass cloth and resin. This is probably the cheapest way to do it, and ironically it is probably the longest lasting.

Thanks.

I will definitely be doing the cloth and resin 1st, but it has very little UV resistance. There must be a top coat to provide the protection.

I don't think you'll have much luck finding epoxy paint that won't respond in some way to UV exposure. The chalky surface described for the Epoxy Paint won't do any harm and probably won't even be noticeable underwater. My local zoo's aquarium uses tanks that are sealed in epoxy and some are over a decade old. I see no signs of deterioration due to UV exposure and they still look good.
