The sealant worked just as described, self leveled around the solar brackets. This use resealed the RV rubber trim around the out side of my RV I replaced. The sealant hardened to a perfect consistency. I will always use this product in the future. 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.
