Amazing product! Will buy again!
Bought some stuff for double the money at the parts store and it was junk. Decided to buy this and will 100% be buying again. Super easy to use.. throw it in a caulking gun and cut the tip.

Good value. Seals great.
I replaced the floor boards in my elcamino, sealed the seams with this product. Works well, dries fast, accepts primer/sealer well.

Seam sealing
I used this to seal the body seams on my 65 mustang that I am restoring. It flows nicely you can tool it but you have to be quick because it starts to skin over stays in place and bonds good
