Love this stuff! Was able to use it to help seal various different parts on my 69 Dodge Dart Project. Has a nice glossy texture and dries pretty quickly. Helps protect my components in my car and keeps them from cracking. It is a good texture for most any projects. I have used it on other applications too. It's nice that it's a versatile project that I can use for almost anything!

A very good product for sealing gutters and skylights. Paints on easily and seals all holes.

This stuff is amazing. I actually used it on the floorboard of my vintage VW and under fender wells. Very durable product and good sound dampening, I used paint brush and paint on very thick. Worked great and basically put a solid layer of rubber on my car for good protection from elements.
