## Description

Marine-Tex is the legendary high-strength repair compound designed for filling, bonding and rebuilding wood, fiberglass, ceramic, glass, metal, masonry and many plastics. Marine-Tex is manufactured to the highest standards to meet the harsh demands of the marine and industrial environments, and solve many problems for home, auto and hobby applications. Marine-Tex is a creamy paste consistency that can be applied on vertical or horizontal surfaces, easily fills gaps, and can be shaped to rebuild damaged components. Marine-Tex paste provides waterproof repairs that can be used with fiberglass tape or cloth to bridge holes and reinforce structural repairs as needed. Emergency and permanent repairs to machinery and equipment, hulls, decks, stripped fasteners, piping and tanks are all easily accomplished with the mighty repair kit. Marine-Tex can be sanded or ground to shape, tapped and drilled, and finished with most common paints and coatings.

Review: Works as described - Use this all the time to repair chips in my fiberglass sailboat. Seals out water just like gelcoat, but much easier and faster to use. Also repaired a garage chain sprocket, that broke in half, and it was as strong as original.
Review: Great Product! Awesome Results. - I used this product to patch an old fiberglass pool slide. I have used many types of patches and putty in the past but this was slightly different in consistency. It was easy to mix and apply. It had the consistency of sticky tar and I was not sure how hard it would setup or cure. I let it dry about 48 hours before attempting to sand it. The product worked awesome. I used a hand held palm sander and had no problems sanding it smooth. Just want to make sure you don't put too much on because it sets up very hard. Once sanded and completely cured, I applied a primer and top coat to the slide. The patched areas are completely perfect, you would never know any repair was done, it looks like new. I would recommend this product to anyone.

## Questions & Answers

**Q: I order the standard size and received the lesser expensive  small 2oz.  What oz is the standard size?**
A: You got the standard size. It's expensive stuff

**Q: A fiberglass lawn tractor hood. Two .25" bolts are molded to a underside bump-out 1.75"x.5" hangs down 1.5" for hood bracket-broke off. Will it hold?**
A: Not sure because of vibration of tractor . We have used it to repair damage on a RV. Fix a humming bird feeder and repair a 4 way  high pressure water valve. Has worked wonderfully. Mark

**Q: Is this product non sagging? Need to repair a few spots on the bottom of a bass boat.**
A: It's an epoxy, and it applies pretty firm. That said, you can sand it flush after installation. It worked well for my needs, but I walked away strongly suspicious that I spent $3 on good epoxy and $7 on legacy branding.

**Q: Need to patch a purple jetski hull. How do you tint the filler?**
A: Yeah…buy tint

### ⭐⭐⭐⭐⭐ Perfect for quick fixes
*by A***R on June 23, 2021*

Easy to mix up on a flat piece of cardboard, has at least a 20 minute pot life (flat cardboard life?), and extremely easy to work with. I found that you can wet your finger after you've applied it and smooth out your application. This makes feathering into the surrounding area much easier and, if you've done it right, means you probably won't have to sand it smooth when it dries. I'll definitely be using this in the future. Dries pure white with a semi-glossy finish when applied how I described. I may even use it to "repaint" areas with significant paint chips where sanding down a huge spot, priming, and multiple coats would be a pain (i.e. spaces with irregular edges larger than 3"x6" due to dock rash, etc).
