    • Sets up fairly quickly.
Size: 12 Pack Color: Black
I bought a seam sealer for my skoolie build. Raised the roof and added galvanealed siding. It flows nicely at the right temp, but sets quickly. It takes me 4 hours for 288 rivets, so I'm having to load up on clecos to fully clamp the sheet against the hat channel. Priced right

    • NOT suitable in Automotive bodywork aplications.
Size: 1 Pack Color: Black
It is NOT fast curing. Takes more than 24 hours for a 1/8" bead. Its messy and not user friendly. If you are thinking of using it to replace traditional butyl automotive type sealer, dont. It takes aggressive solvents to clean it off fingers or anything else. It may be great for HVAC and other type work, but NOT for automotive bodywork. ... show more
