Sealing ply, Eposeal 300 or West Systems?

[Yellow Ballad]

I'm favouring Eposeal as it can be re-coated within 24hrs and it has a long work time (So I've read, I'm assuming it doesn't blush like West Systems). However looking online once you add on delivery it's not far off the price of the WS epoxy I can get from the local shop.

Is there a benefit for one over the other? I've only ever used WS before and rubbing back the blush took the longest thing of the whole job. (I should have used peel ply)

Cheers

I'm currently using Low Viscosity MAS epoxy on my plywood project - no blush - available via East Coast Fibreglass. 2:1 ratio. Easy to use.

Just thought I'd throw that into the mix.

If this is your locker project then epoxy coating is OTT. Just use conventional coatings - either universal primer, undercoat and topcoat or as I suggested on your other thread Danboline.

Partially, I need to make a new battery tray/box to relocate the batteries out of the V-berth (to shorted the cable runs and neaten everything up). It's going to be quite a feat and I don't want to have to have to remake it again in my lifetime if I can help it.

But getting back to the locker hatches, the lazarette floor/liners have been saturated in diesel/grease/sea water from decades of use and i'm thinking for the money saved using WBP giving them a coat of epoxy before Danboline satisfies my belt and braces mentality.

I can only go by my experience of owning a ply boat (built in 1965) for 37 years and have never coated either marine ply or WPB with anything other than conventional coatings, particularly Danboline. Used plenty of epoxy for other purposes on the boat where there is serious danger of water getting into end grain or for structural applications. Never had any problems and the bits such as you are making I made in 1992 in a major refit. Still as good as the day I installed them.

I think it's just my over cautious, belt and braces "it's all going to fall apart and the fenders are going to get tangled in boat hooks and brushes" paranoid mind taking over. Plus I want to do a good job once, but I suppose 25 years can't be called a bad job

Good to know, thanks, WBP and Danboline it is.
