Easy to apply, looks like a good seal
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.
