## Description

Product description

Review: Tight strong hold ! - Quality product. Waterproof and creates a tight seal. Clean white looks great, higher price than caulk or silicone but for this application I think it’s a good value for the money. Used it install a new roof vent on inclosed trailer.
Review: Easy to apply, holds up well so far - I can't give you a scientific or long-term review of this stuff, but I used it for the first time a couple of weeks ago just to reinforce some weak areas with the previous sealant had bubbled up and broke or cracked. Yeah, it's more of a band-aid application, but it went on easily, had just the right viscosity to spread and level without going too thin. I gave it a try because it was a bit better price, but it seems to be a fine product. Between then and now, it experience rain, sun, and cold, and went on a 200-mile road trip. When I checked it yesterday, it looked exactly as it did when I applied it... smooth and bright. So, I can't speak for long-term durability, but so far, so good. When I do a more thorough job, I will order this same stuff again.

## Features

- SEAMS SEALED, WORRIES GONE — While you're roasting marshmallows, our self-leveling RV caulking lap sealant is working overtime on those pesky roof seams and vents. Unlike ordinary camper roof sealant, ours stays flexible from scorching desert heat to frosty mountain mornings. Because nobody wants to play "find that drip" at 2 a.m
- ONE TUBE DOES THE TRICK — Each 10oz tube covers 25 linear feet of adventure protection. Our self-leveling RV roof sealant flows right where you need it—around vents, along edges, and into seams. Sticks like crazy to EPDM rubber roof, TPO, metal, and fiberglass without the complicated prep work. That's more time for campfire stories
- OUTLASTS THE TOUGHEST Conditions — Other lap sealant for RV roofs products make you reapply yearly (fun, right?). Meanwhile, our RV Roof Lap Sealant keeps its grip and flexibility for the long haul. We've engineered it to withstand UV exposure, temperature swings, and all the bumps of the road, so you can spend more time exploring and less time maintaining
- SO EASY YOUR DOG COULD DO IT — Almost. Our self-leveling roof sealant flows smoothly into seams and around fixtures, doing half the work for you. Clean, cut, apply, done—then grab a cold one. Even if you think "caulk gun" sounds like a water toy, you'll get professional-looking results. That's why we're the best sealant for RV exterior seam repairs
- SAFE FOR THE WHOLE CREW — Our caulking sealant formula is non-hazardous with no solvents. Unlike sketchy silicone roof sealant options, ours won't make you evacuate the campsite. Safe around kids, pets, and your morning coffee. Because your weekend getaway shouldn't require a hazmat suit

### ⭐⭐⭐⭐ Shelf life
*by M***O on October 12, 2023*

This product seems to work just fine. The only thing that was disappointing is that it has a two year self life, and the tube I received expires in five months. This means that I have to discard a pretty full tube.
