Default Plywood enclosure coatings (paint, carpet, tolex, etc.)

I have used all kinds of interior and exterior surface treatments for durability. Last time I bought a fe gallons of high wuality fibergalssing epoxy, mixed it up, and brushed it on. Worked great, the only thing to hold up better was actually fiberglassing the exterior. I thinned the first coat of epoxy for deep penetration into the wood. I used epoxy with little "blush" so ew chemicals come out to the surface, so it was a good choice for multiple coates without needing any treatments between coats. Then I carpeted over the epoxy.

Now I moved and I don't really know where to buy boat building suppiles or fiberglassing supplies, but I could find out (I'm near a big harbor again).

But I'm seeing some durable floor treatments. There's one-part and two-part epoxy garage floor paints, and the price even seems reasonable. And they're evailable right at my local LOWES or Home Depot.

Then there's some ruberized floor stuff they use for gyms, applied to concrete floors. Also very durable.

I've heard of people putting on pickup truck "liquid bedliner"

When I used real fiberglassing epoxy, I thinned it with Klenk's tub and tile epoxy thinner (toluole and zylene and alcohol). In fact, I painted some cabinets with Klenk's tub and tile epoxy. But the EPA pretty much put them out of business.

Anybody ever tried painting PA enclosures with tub & tile epoxy or with garage floor epoxy or liquid truck bed protectors?

I haven't tried those products, but there's a West Marine in Long Beach. They'll sell you the West System epoxy, which is pretty good stuff.

I've used epoxy for about everything. Factories use it for walls and machines, way more durable than oil or water base paint. Sherwin Williams even has a water based epoxy topcoat that avoids the evil smell. The toughest thing I know is Sherwin Williams recoatable epoxy primer, about $80 for a 2 gallon set and smells awful. but you put some water based epoxy top coat over that, pretty tough. Dull finish. Requires sanding if brush painted before the finish coat. Porter paints has a similar product. Better looking topcoat is SW Tileclad, that dries to a shiny gloss white finish. Really vile smelling.
I've used the epoxy floor patch on floors, it has sand in it. Sand is great for compressive loads, but not an instrument coating.
Dupont has an epoxy spray paint. So poisonous, requires a forced air mask for the painter. Imron. Looks great though, street rod people use it a lot.
I use bondo epoxy/fiberglass mix auto body compound to patch rotted floors in bathrooms and kitchens. I'm no respector of labels. Not since I found the dentist was using something like it in my teeth.

Never heard of Duratex. What is it?

I've used Imron, a catalyzed acrylic lacquer, and plenty of catalyzed acrylic enamels for cars, but my cabinets are more industrial; I don't intend to do the kind of prep an automotive finish requires.

bondo and many auto patch fiberglass kits are catalyzed polyester not what I consider real epoxy.

I'm surprised nobody's tried the new garage floor epoxies on industrial cabinets yet. I wish I had a sample to play with.

I'll definitely look into West Marine Thursday night, as Thurs. is payday.

Its a water based catalyzed coating that is specifically designed for speaker enclosures. Goes on really nice and has very little odour( you can coat your boxes in your house ) dry time is temp dependant and finish is humidity dependant but I haven't had any problems with it glazing. I think it is what JBL uses for their boxes. Look up Acrytech coatings, they ship right to your door.

Is it cheap? 'cause the boating epoxy is clear and high quality but 4 times what I used to pay. I used to pay about $200 for a box of 4 gallons of resin and a box of 4 gallons of hardener. Now it's $99 for a gallon and $25 for a quart of hardener.

Alright, that's close to half the price of epoxy.

I never did like the look of carpet, though it does hide the knocks and dents.

I paid $60 for my last gallon plus shipping, one gallon should cover about 80 to 100 square feet. Maybe more. I just finished a double 18" enclosure, which was around 38 square feet and. There's about 60% of the gallon left, so yeah pretty good coverage
