Most resilient coating for epoxy coated wood?

[ridgy]

Replacing some bits and pieces like an anchor well cover.
Epoxy coated 12mm ply but what top coat for long life? Inclined for exterior white gloss but open to suggestions that aren't 12 coats of varnish.
Appearance not important.

I am not qualified/experienced to advise on pros-cons but if you go down the route of gelcoat, a few relevant videos recently popped up from a Youtube channel I subscribe to. Might be worth a look.

How To Gelcoat over Fiberglassed Plywood - The 3 BEST WAYS

Toughest would be a two pack epoxy paint, followed by 2 pack polyurethane. Easiest to repaint and tough-ish would be Danboline or similar

I use 2 pack polyurethane over West epoxy, it gives a very tough hardwearing finish. But it's quite a lot more work than a single pack paint.

Single pack isn't as resistant as two pack, but it has the advantage that you can slap on a fresh coat with a minimum of fuss.

Other than remaking the cover out of 8mm stainless steel, I don't think you're going to get a finish that will stand up to having an anchor bounced off it, so I'd be inclined to go for ease of repair over ultimate resistance.

Exactly. We almost all paint our XODs with car paint, cos it’s easy to repair after a ding dong at the leeward mark. They are epoxy coated under the topcoat.

Epoxy coated wooden old boats??!! Shocking, instant rot and boat death

Not so. It depends on the construction and how it’s done. Coating epoxy on the outside of a wooden dinghy, leaving the inside with conventional finishes works very well. Coating an old boat inside and out with epoxy traps any moisture and causes rot.
My Finn (hot moulded veneers) was coated with epoxy on the outside only about 30 years ago. It’s still in very good condition. It has conventional varnish on the inside and the outside is rubbed down and re coated with one pack finish every few years.

 

[MisterBaxter]

For an anchor well it might actually be worth considering glueing a layer of some very hard-wearing material onto the high wear areas. Maybe phenolic/Tufnol as used on flatbed trailers?
Edit - just reread and saw that it's the well cover... In which case paint would be fine, although still worth thinking about strips of tough material in the places that sit on the edge of the well and get bashed every time the cover goes back on.

Far from it, if done correctly. The XOD fleet is still sailing because a vast majority of boats are epoxied. Been done a long time too, so much for instant. We own one that was done at the dawn of the epoxy era, no rot, still competitive.

 

[oldbloke]

Sorry, forgot the emojis. I too have an epoxied wooden boat , but usually when epoxying is mentioned there is a great pile on decrying it as boat murder

Absolute rubbish

 

[HunterWanderer]

If the epoxy has hardened then it has to be sanded to get a key. If not use a waterbased eggshell topcoat onto tacky epoxy. Unlike polyester resin, epoxy cures when in contact with water
