Review: Best RV Sealant Ever... - Works better than any standard RV sealant. I always use marine quality items on my RV... They last longer and perform better on the road.
Review: If this can't seal it, it can't be sealed - Moving to a new house, we unknowingly let a vinyl lined hot tub (Softub) sit in the summer air upside down for three months. BIG mistake. This resulted in several rips and tears (including one 2 feet by 6 inches!) in the inverted sagging of the long-water-dependant vinyl. We thought our hot tub was a goner. Tried numerous hot tub rip repair kits, and none of them worked well enough for this major repair job. The hot tub was aging and had served us well for nearly a decade, so we didn't want to purchase a complete replacement liner because of the price - either fix it or toss it. Vinyl patches provided were strong enough, but none of the vinyl patch kit adhesives were able to really withstand the stresses of a full 300 gallon water load on the stretchable vinyl. We made all repairs while tub was empty so as to obtain the best seal. In addition to vinyl-specific glues and patch kit adhesives, we tried vinyl contact cement, shower pan liner adhesive, and every single type of PVC/vinyl glue at the local home improvement store. Not even Loctite plastic bonder would hold once the hot tub was full and chlorine was added to the water. As a last resort, we decided to give this "below the waterline" "hull repair" "permanently flexible" sealant a try - and WOW! it sticks to everything. We gave it a good cure of several days (this was outdoors in winter, so took a bit longer). We used this to adhere the vinyl patches to the tub' vinyl liner, to each other, and to feather around the edges so as to prevent bathers from tearing up the sides or water working the sides loose from the jets. 2 months in to this repair, from which no other product/system/glue previously lasted longer than a week. Much impressed by the miracles of modern petroleum strength commercial chemical derivatives - nicely done 3M!

## Questions & Answers

**Q: is it paintable?**
A: I did use a permanent marker to match my convertible to to the glued glass window

**Q: Can I use this as a glue/sealer on my wooden hot tub?**
A: This is low strength. I would choose at least a medium strength silicone sealer.

**Q: Will this work to seal the top on a raised roof van?**
A: 3M Marine 4000 UV Adhesive is an excellent UV resistant caulk. The 4000 is especially designed for fiberglas and teak. If you want the toughest structural waterproof joint use the 3M 5200. Do not use the 5200 if you plan to take the raised part off. Once cured the 5200 forms a tenacious glued together joint.

**Q: does this caulk contain polyurethan?**
A: No, unless it goes by another name.  I did not see it listed on the label.  -Jim

### ⭐⭐⭐⭐⭐ Excellent for Sealing RV Roofs
*by K***Y on June 30, 2023*

This is an excellent product overall. While marketed as a marine sealant, it can be used in other applications where a waterproof, UV resistant seal is needed. I previously used this to seal around mounting brackets for solar panels on an RV roof. Now, I am removing dicor sealant around vents and other openings on the roof and using this instead. Based on my experience with it around the solar panel mounts, it seems to be far superior to dicor and similar products sold as roof sealant. It sets up quickly and acts as both a sealant and an additional bonding agent. I suspect it is strong enough to hold the solar panels by itself (I used VHB tape as well). The only downside I have found is it does not keep its shiny white appearance over time; it gradually turns dull aand yellowish, but as long as you use it where the appearance does not matter it is a great product.
