A real and solid product that seals body seams on automotive and industrial applications. Paintable and very strong.

Works great, I had plenty of working time with it in 75 degree weather. It bonds great to properly prepared surface. Cures hard in about 8 hrs at 75 degrees.

Easy to use 2 part epoxy for sealing large joints. The mixing tip is quite ingenious and mixes 1:1 epoxy as fast as you can work. You will need to purchase a chalk type gun to be effective.

I love this stuff because of the fill quality, and it seals up tight and dries very well. Always has a very nice finish to it.
