Good two-part epoxy paint
I used this paint on a marine-plywood rowing boat. As an epoxy, it bonds well with wood and with scuffed coast of epoxy. This is my below-the-waterline barrier coat and I'm also using it on the interior planks of the dinghy as a waterproof primer. This paint is the consistency of mayonnaise with not much liquid in the container. You'll want an electric drill-powered paint mixer to thoroughly mix the paint and the catalyst. It rolls on thick and easy and doesn't sag but the finish is not smooth like topside paint. Use as-is to protect fiberglass boat hulls. I'll leave it as-is below the waterline but am using two coats so I can sand it smooth and fill with a primer above the waterline before applying topside paint. Also, the directions say to let the paint sit after mixing. Pot life is long so no need to hurry like you would with 5:1 epoxy.

Good stuff
Great primer for boat hulls, etc Dries to a tough film overnight yet still easy to sand. Says you can’t apply over a 1 part paint, but I used it over dry, sanded Kilz 3 and it was fine. First gallon I purchased from Amazon. I found out the hard way Amazon paint products are not returnable so I looked around. Thats when I found Jamestown Distributors. Same pricing and delivery timing, but included a paint suit, stir stick, roller & pan, roll of tape, and tack cloth, plus’s 10% discount. Not sure of their return policy, but it can’t be worse and the rest is better. Even shipping. Amazons stuff was all dented, Jamestown’s arrived in perfect condition.

Great way to restore an old jon boat!
I had a rough looking jon boat that needed new interior paint. I just refinished with this prime coat, before doing the final painting. It is not the easiest paint to work with, but if you prepare it goes well and gives great results. I used both a small 2" brush and a 9" roller. As others mentioned, I did a 3:1:1 mix of paint, hardener and thinner. The paint is SUPER THICK in the can, so thinning it down a little in the can will reduce waste and make pouring a little easier. The working time is very long. I had no problem painting the entire interior of the boat, which took more than an hour. Towards the end, the roller does get a little harder to use as it loses absorption. Plan all your work ahead and you'll be happy with this. I used empty water bottles to measure paint, hardener and thinner. I then dumped those into a milk jug with the top cut out and mixed it thoroughly with a mixer attachment on a cordless drill. Doing those steps with make the job go more smoothly.

Seems to work well for my bilge
Used it as a primer coat for Interlux BilgeKote in the bilge of a boat while engine and outdrive was removed for rebuilding. All application surfaces were cleaned and degreased. The surfaces over which this was applied was a mix of epoxy, JB Weld, and gel coat. Areas were painted with a 4" foam roller and a 2" disposable brush. The foam roller purchased from the local home-doodle store started to crack and get limp right around the time I finished (1/2 hour later) apparently due to the chemicals in the primer attacking the foam. Primer adhered quite well to all surfaces, even the smooth areas of the gel coat which was not scuffed. This stuff just plain sticks! One quart was ample with about 6 ounces to spare for any touch-up. Epoxy mixed well with drill and mixing tool. Clean up with Xylene was painless. I have yet to apply the BilgeKote, but looking at the instructions, I expect no issues.

Very happy with the end result.
I own a 12' fiberglass boat. One quart ,thinned out properly using Thinner 200, was able to coat the entire inside of the boat twice. So I was able to achieve the recommended coats of 4-5 by using two quarts. I applied with a 9 inch roller with a 3/16" nap. (I didn't tip and roll) All supplies were made by Wooster. Be sure to follow instructions carefully. One side note is to buy a mixer attachment for a drill. The base (paint) is very thick and needs to be mixed thoroughly before mixing with the hardener. Stir for 2 min. Induce 15min ,thin and apply. I have 0 complaints, and will buy again for the next time I need to paint my boat. It's important your roller nap is 3/16" for this two part Primer. Mix the proper amounts and it should go smooth like my experience. Good luck folks. Don't cut corners and get yourself some Wooster supplies .
