Travaco RM330K Marine-Tex Gluvit Waterproof Epoxy Sealer - 2 lbs.

I normally would not pay this price for an epoxy, but since it is supposed to be so good for sealing aluminum and remain flexible I gave it a shot. I cannot yet attest as to how well this is going to seal my leaks because I have many more areas to seal before dropping the boat in to check for leaks. This review is to dispute negative reviews where people are claiming that Gluvit takes several days to set.I mixed at the 5:1 ratio in the directions using a $20 kitchen scale that has the ability to weigh in grams.At first I was sceptical, because it seemed to take longer to begin to gel than the epoxy I used to build the transom in my other boat. But after about two hours it was thickening up, so I became hopeful. When I checked it first thing this morning, about 17 hours after being poured yesterday afternoon, it was set hard as a rock.Easy to use. Plenty of working time. Sets up nicely. If it seals like I'm sure it will, then it will be my go-to epoxy for these types of repairs.

I ordered this for my husband to repair his he said it was great to work with.

I applied this product to my 14 foot jon boat after I had re-riveted the entire boat. I removed all the old paint down to the metal. I then applied the product. It went on smooth and the curing time allowed me time to get a smooth coat. I allowed it to cure for 48 hours. I then did a light sanding with 120 sand paper. The marine paint adhered very good. I have had the boat out several times and the interior of the boat is absolutely dry. Looking forward to many years of fishing with a leak proof boar.

This was my first time using Gluvit on the bottom of one of my boats . I used a 6 inch wire cup brush on my large grinder and did the whole bottom of the boat , it looked super . Then I masked about 1 1/2 inch out from the keel and had the boat rolled up on its side so the Gluvit would flow into and under the keel strip . I only painted up to the deepest part of the keel and let it sit for a day . The next day I rolled the boat up on its other side and repeated the process , it seems to have bonded nicely to the day old Gluvit . It flowed into all the low spots and leveled out nicely . After a two day dry it was back on the trailer and headed to water . AAA+++ ( P.S. I used a cheap 2 inch paint brush , I dont recommend using a roller )

My first order was damaged. The large can lid came open and spilled goop all in the box. Thank goodness for the plastic bag it was in, but some did leak out on the box (reason for 4 stars). Amazon refunded my money pretty quick, so kudos to them. As far as easy to use, it's not the easiest stuff I've ever used. It has the consistency of a thick paint, so when applying it to vertical or over head parts it will drip, you just have to keep going over the same area so you don't end up with stalagmites hanging from your project. I applied the Gluvit to the keel of my aluminum boat in an attempt to stop the loose rivet leaks while it was on the boat trailer because I had no way of turning it over. Directions state it has a working time of 90 minutes, I found it's a little longer than that. Do not buy this stuff thinking it will fill gaps because it will not. I had seams less than 1/8 of an inch and it just won't fill the gap. Of course the directions will tell you to use a gap filler on those areas first. It will however seal loose rivets as long as they are not gapped very far. Prep is key, so wire brush or sand the area to be treated, clean with a good solvent afterward, such as paint thinner of acetone. Use the blue painters tape to tape off the area you will be applying or you will end up with epoxy swipes that will leave a shine where you do not want it. Make sure you remove the painters tape before the epoxy hardens or you will have to live with the tape on your project. I used a cheap paint brush to apply the epoxy and it performed great. The two pound can covered an area of about a 6" wide path 17' long with about two decent coats and enough left over to dab some on handful of pin holes on the transom cause by electrolysis. The epoxy was tacky after about 4 or 5 hours and appeared to be hardened over night. Cure time is 48 hours according to the directions, I'll give a few weeks. Ultraviolet light will cause it to change colors according to the directions, so plan on painting over it. I plan on using an armored truck bed coating because I have plenty left over from another project and it will protect the epoxy better than regular paint. Wear gloves and an old long sleeve shirt your willing to trash or you will have a bad day when your finally done. Ask me how I know about the shirt. The big question is, Would I buy this again? Probably, but I would definitely fill the seam gaps with a marine grade putty first. Even the smallest gaps will require a filler. Hope this helps you folks on whether it will work for you.

I have an old 1236 jon boat and man did it leak. I tried bed liner spray and JB Weld Marine both seperate and together. That didn't work at all. Read about this product and although I believe that if it sounds too good to be true, it probably is, I sprung for a quart anyway. I cleaned off all of the bedliner and JB Weld that I could, replaced all the rivits using Flex Seal on each individual rivit and allowed that to cure for a week I then coated just the rivits with Gluvit. When I saw that I had plenty left, I coated with a roller, the entire bottom of the boat with Gluvit. Let that cure for a week and then applied 3 coats of bedliner, again with a roller. Let that cure for a couple of weeks. I have not had a drop of water come in through the bottom of the boat since even after beaching it occationally on accident on a concrete boat ramp. Going on six months now. and its used at last 3 times a week in lakes, rivers and bays. Boat is trailerd, powered by a 6hp Mercury. Even engine vibration and driving it up on the trailer has not forced a leak. I am shocked at how this product worked and will be the first to let you know if I have a failure. Not too worried though after recently inspecting the bottom of the boat. Looks perfect.
