Review: This is remarkable stuff - I did a lot of tests with this stuff with goal of using for my shower. It passed all my tests well. This stuff has no odder. Superb. I scrubbed everything with mineral spirts and Used this product. You need a good quality caulking gun. This stuff is a little stiff but not bad, There is a learning curve to this so practice on something else so you know what your getting into. It sticks well and am hoping shower is good for years now. If you want to run your finger down it to smooth it out, use mineral spirts on you glove first and it will look good. For me now time will tell. Big note: This stuff adheres to epdm Rubber roof very well. after a week tryed pulling rubber apart and the plies of rubber split apart before the pl marine let go. very impressed. rubber roof must be very clean.

## Questions & Answers

**Q: is this product clear**
A: No, this product is not clear.  It's white.

**Q: Rain barrel leaking thru small cracks in plastic ring/surface surrounding where faucet screws in. will this fix leak? or loctite epoxy better? thanks!**
A: Used this on a koi pond skimmer extension I made from lexan which has remained leak free for 3 years with water running over it from a pool pump . So two different forms of plastic glued without leaks.  This is some sticky sealant so I would say it would do the job. Sand the cracks just to roughup the surface with some 360 grit sandpaper and this sealant should fix your problem , it's flexable after it cures so movement won't break the seal .  I also used this to glue a John deere riding mower seat back on the seat frame  and it is still holding.  Locite makes quality thread lockers and sealants and I have never had a bad day with their products.

**Q: Will it work to hold a corner bumper to a metal dock?**
A: Not by itself.  You will need some fastener as well.  This stuff does not bond well to some plastics such as HDPE or polypropylene.

**Q: Will this work with EPS/XPS Foamboard? looking to seal DIY camper shell to trailer bed. Shell is 2" Pink foamboard sandwich covered with 1/8" plywood.**
A: aIt will work but there are better alternatives out there it is more of a sealant it has good adhesion but takes 24 hours to reach full strength

### ⭐⭐⭐⭐⭐ This is awesome stuff! Recommended!
*by R***. on February 18, 2025*

I had a difficult problem. I bought a rainspout adapter which diverts water outside of the aluminum downspout into a water barrel. Problem was that it is made of rubber, flat, and up against an aluminum and wavey shaped downspout. Of course it leaked like crazy. If only I could find some way to seal this to stop the leaking. This stuff did the trick. It is white, and a very thick consistency. Formed a perfect seal and in addition holds very strong. It sticks to everything including your hands so be careful. Bought another tube for just in case. Unused product will stay usable in the tube for a while, but for longer term, you may want to place it into another very air-tight container. Highly recommended.
