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

This stuff is expensive but it is worth every penny. This Seal is PERMANENT and senna that it will never leak. I used it around rivets on a Jon boat and it worked fantastic. Be sure to mix the hardener correctly.

Found a used and abused v-hull aluminum boat with many loose and a few missing rivets in the bow, which leaked about 3 gallons an hour. After some wire brush cleanup to remove the previous owners body putty, and a few screws to fill the missing rivets, I applied a coat of gluvit. It went on easily ( I used a roller) and appeared to be setting up fine. But in not wanting to waste it, I applied the rest of the can too soon, and found some runs the next day. It would have been fine if I had just thrown away the excess. Allowing a couple of days for it to set up, it dried to a slick shiny finish. A lake test proved gluvit had done the job and there were no more leaks. Only one problem remained- even though it looks white in the can, gluvit is slightly brown tinted transparent when it dries, so it was quite noticeable on my white boat. However, a second light coat with an ounce or so of white pigment (amazon - White Pigment for Epoxy Resin, Gelcoat, Paint, Latex - 4 oz) mixed in looks Perfect. That was last year, and now, after more than 200 hours on the lake, it still looks great and I only run the bilge pump after a rain. I highly recommend gluvit for both it's effectiveness and ease of application.

This stuff is amazing! Works great!

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.

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.

Carefully packaged. Arrived on time

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 )

Item worked exactly as intended for my 14ft aluminum boat!
