Marine TexRM320K Rapid-Set

Strong , smooth , no grit .

This is pretty good and quick curing epoxy. I used it on the threads of some screws I installed in the transom of my boat and expect them to be solid and sealed well with this stuff.I have also used it to glue down some stainless steel studs for mounting stuff to the inside hull of my boat. With the correct studs made for the application I suspect it is as strong if not stronger then running a screw into the fiberglass.One thing I will point out is this stuff is black in color. The package doesn't mention color that I saw and by its appearance you would think this stuff is white. I will reiterate this epoxy is black in color so be aware of that when you purchase it.

I guess there was a nail or something sticking out of a dock I used recently. When I was getting off the water I found I had a good chip just above the u-bolt on the bow. This product was suggested to me so I gave it a try.It was easy to use and easy to apply. It started to set really quick so be sure you are really ready to use it before you mix it and then work steady as it will start to get hard fast.It is easily sandable and paintable although I have not sprayed it yet. Its ready. I have been on the water since and it held tight and shows no signs of needing anymore work.

Caution: packaging does NOT indicate product color anywhere! I ordered white, but unfortunately received gray.Company gave full refund, so no issues there. From the little bit I mixed, it seems hard as granite. No idea how it’ll hold up to drilling, tapping etc; but my little test blob seems quite sturdy.

Unless you read the description carefully, you may skip over the fact that this product is actually GRAY. I had ordered this product in a hurry thinking it was a rapid setting version of the regular Marine-Tex used on boat hulls, etc. It is the GRAY version used for machinery, non-visible areas, etc.Other than the fact that the color wasn't clearly stated, the product is actually pretty great and works exactly as described.

Used it this time to repair an exhaust manifold and worked awsome. In the past I have used it to repair a fuel tank on a tractor trailer and have used it to repair the pump on my pressure washer that had some water in it that froze and cracked the housing .Great stuff!!

Marine Tex is fantastic stuff, and this quick-dry works really, really well. I'm used to the original Marine Tex that would take a long time to dry before you could sand and paint. This stuff really saves time and works just as well. I filled some screw holes in some molded plastic (and fiberglass), sanded smooth and painted, all in a very short time. You can find so many uses for it.

Works great at filling in small nicks and chips in the fiberglass gelcoat of a 50 year old MGB Hardtop I'm restoring/prepping for paint. Also used the larger size longer setting Marine Tex epoxy putty to skim-coat a couple of areas worn down to the fiberglass where fiberglass threads were showing, and fill a 1/4" deep 2" long gouge in the top back edge of the hardtop. In all, fantastic products.
