Questions about this item
Will the 760 UV Polymer Adhesive Sealant bond reliably to the fiberglass and metal surfaces I am keeping on my current project?
The sealant is formulated for use on fiberglass, metal, plastic and wood, providing a flexible, UV-resistant bond across those substrates.
How can I verify the 760 sealant has cured correctly after the one-day full cure time?
After one day the bead should be firm, flexible and paintable with no tackiness, showing the 100 percent elongation property has been reached.
Does the 10 oz cartridge include a nozzle or caulking gun, or must I buy them separately?
The package contains only the 10 oz cartridge; a compatible caulking gun and nozzle must be purchased separately.
