Comments

TJ: We have a school bus conversion, and this is our go-to method to seal up any leaky points in the roof or walls or anywhere else. We also use this any time we need to drill through the roof and it stops any leaks from ever forming. It's a bit pricey, but it's well worth it. Highly recommend.

Andy: I bought the clear to seal external aluminum sheet metal seams on my box truck body. I tried using painters tape to get straight edges where I applied the sealant..don’t waste you time doing this it won’t make a straight edge. Ended up just laying a bead down and working it with my finger. Good stuff other than that.

James Gleason: I used this for my 1966 Mustang after repairing the floors and replacing the rear quarters. It went down easy and dried quickly. Paint went on with out a hitch.
