Amazing GOOP 5400060 Coat-It Epoxy Sealer Adhesive Kit - 8 lb

Awesome product if you follow the directions to the LETTER! I used a small digital kitchen scale to measure out the 1/7 ratio. 14oz of the big jug and 2oz of the smaller jug (one pound of epoxy) and it worked perfectly!Starting in the morning it was about 65° outside and I had about 30 minutes working time until it was starting to harden in my mixing container. Later in the day in the mid 70's the working time only went down by 10 minutes or so. You'll definitely be able to tell the difference and it doesn't happen all at once. I was able to still apply it easily when it was about the consistency of cake batter without any issues. Just make sure prior to mixing you have all your tools and the work piece ready to rock and roll and you'll be just fine.So far its held up under a 14 foot aluminum boat slamming through wakes and beaching on coarse sandy/rocky shores with zero sign of wear. Approximately 15 days on the lake so I'm pretty happy with it. Oh and zero leaking rivets as well!Edit: 6-6-18Product STILL working like new, hundreds of fishing trips, hundreds of boat launches and recoveries, hundreds of miles on gravel and dirt roads, even a few trolling trips through 32 degree water with floating ice chunks and absolutely zero signs of wear. Finally a product that actually works!Edit 1-22-21Still absolutely no signs of wear. The paint I applied over the epoxy is definitely showing signs of wear (abuse), but the epoxy is still holding strong. Still no leaks!Edit 1-18-23We actually just sold the boat, but the epoxy was still 100% intact. Showed the new buyers the epoxy repair and while looking at it there was still virtually no signs of wear. The paint over the epoxy has completely worn away, with only minimal scratches where we'd presumably beached the boat on a rocky shore somewhere. Good stuff, definitely keeping this stuff in mind for the next repair if (when) needed.

I’m very pleased with the Goop Coat It. I don’t recommend going against the manufacturer’s instructions, but I added blue dye and silver and blue glitter into the mix, and am a big fan of how it turned out. Do not apply with a normal cheap foam roller as other reviewers have stated.If I were to do it again, I would spread the goop with a putty knife and the roll over with a non-absorbent roller.I started with a cheap roller, and then was forced to use just a paint brush, which did not spread great due to the thick consistency of the goop. So for my first layer on my 14’ boat I used approximately 3/4 of the 8 pound can, which prevented me from being able due to do 2 even layers. (Completely my fault)Overall, I feel very confident that the bottom of my boat’s hull is going to be way more protected. With the price, definitely go with Goop. Even if you have to apply it every two years it’s still cheaper and way less finicky than the other boat slick-bottom coating options.

I patched a small aluminum boat that had been hit with shotgun pellets. Not a drop of water after. It does dry fast so be ready to start spreading it as soon as you mix it. Very tough epoxy.

Just what is says it is

Sealed up the holes and gets rock hard just needed to do it during the summer not winter with out a heated garage so the finish was rough and had to sand it down and reapply (fyi its gray not black)

Works great. 3rd time buying this brand.

I would NOT recommend this product, it does not cover evenly and has a tendency to run on vertical surfaces no matter how thin or light you apply it. I wanted to do two light coats on my 14' boat. The first coat I mixed and it seemed to take forever to harden even though it was 85°. I weighed out the product using a scale as per the instructions and applied it with a small brush as I wanted to do each seam and rivit individually before coating the whole boat. The product ran before it hardened. I thought "no matter" as I was doing a second coat and it would cover it. I mixed the second batch and used a roller for it and it also ran. I looks to me like the suspended stuff thats in it is to heavy for the material to support so the slightest angle is going to cause it to run. When it does cure your left with heavy spots where the suspended materials accumulated which is gray and other spots that are clear where it's just the coating. It makes your boat look like it was painted with finger paints in a kindergarten class. Only time will tell if it's going to seal and hold up but if I wanted something splotchy, uneven and different colors I would have just used plumbers putty like the last owner did. If I ever have to do another boat I will use plumbers putty and paint and do the whole thing for 15% of the cost of this junk.

Not a slick as I was hoping, but slick enough. Seems tough. It is some what translucent so if used in a high visibility area you would want to prime a solid color first. All in all I'm pleased and would recommend.
