Review: EXCELLENT, WORKED GREAT TO STOP THE LEAK IN OUR CAMPER. - Had a slight leak in the caulking of our “new to us” camper so we removed the caulking and used this #M Marine Sealent. Cure time was fairly fast, just as advertised. We were expecting major storms the next several days and after 6 straight days of hard rain we were pleased there was no leaking. The application was easy. I recommend cutting the tip at an angle to get a small beading. It did dry with slight coloration. It is not a white/white. I felt the cost was a bit much, but it’s the first time I’ve bought sealant of this nature. That said…. The price I spent on this single tube- and the excellent job it did at stopping the leak was priceless! Will buy again when/ if the need arises in any other locations on the camper. So in that sense, GREAT value for our money!!
Review: Came Smashed - This came packed between 2 12volt batteries. Needless to say fedup X handled with care( that they would ruin whatever was inside.) And that they accomplished as well as a professional demo team could! I used a spatula for what I could but there was a lot of waste, I will be buying at home dep. unless desertcart teaches the shipping packer of theirs how to pack, desertcart should have their people put in a shipped or packed by slip to get feedback on an employee that doesn't care about the quality of their work. Other than that the product was Great!

## Questions & Answers

**Q: Will this product go bad if it isn't all used within 24 hours after removing the seal?**
A: Not if you reseal it (remove and clean the nipple and put a nail or bolt in the tube opening) stick it in a ziplock and put it in the refrigerator. Take it out before next use and let it come up to room temperature or it will be very thick and hard to dispense.

**Q: Can this sealant be used to fill in grout between tiles in the shower? Is it hot waterproof?**
A: This a marine and Rv’s sealer  for vehicles that requires movement only,  not for shower.

**Q: Will this adhere a flap down on an (epmd) rubber pond liner? i don’t need it sealed i just want it to stay layer flat.**
A: It does say in the specs that it remains flexible, so it should work.  You might have to scuff up the surface a little to give it a little more 'tooth', but see if 3M has anymore information on their site for this product.  Have you considered using an adhesive specifically made for epdm?  EPDM is used on roofs, so an adhesive should be easily found.

**Q: Can you get this clear?**
A: Any color you want, as long as it's white
