Sikaflex-291 LOT, White, Marine Adhesive and sealant, General All-Purpose PU Adhesive with Long Open time, 10.1 fl. oz

Best caulk I’ve ever had the pleasure to work with. Filled the cracks like none other. You know, I was debating the Black Caulk, because I thought it might be more filling, but the white Marine Caulk, was enough to get the job done.

I used this to attach a heavy duty rub rail on my old BW Outrage (belt and suspenders approach, I didn't trust that the screws that came with the rub rail would work). It's been six months since I did the work and it seems to be holding well. Cures somewhat quickly which makes it tricky to use on a large area in summer heat. I'd use it again before the #M product.

I used it to seal between the body and the bottom pan of a 1970s VW Beetle I'm rebuilding. It'll take me months to find if the seal provided by this product is durable. But for now, it looks encouraging. Also, it is rated for "below the waterline", and that should be more than sufficient overkill for a Volkswagen. As I had to apply the sealant from below the car, it dripped a little bit but not badly. The product flows into place readily and can be smoothed, like caulk, with a gloved (!!!) finger. Go without gloves and have a very messy clean-up coming. The product dries to a deep glossy black. As it is paintable, I plan to spray the bottom of the car with undercoating for protection. The seals cured overnight and look confidence-inspiring.

Great for the boat seams

Muy bueno, aunque debe saber que demora unas 48 horas para que seque bien y más si es muy grande el grosor que aplicó pero calidad extrema

as described
