Mastix
A trimmable joint and end lap sealing tape for metal roofing and wall jobs. Mastix is a high quality adhesive on a roll...the roll won't telescope from heat before installation, and Mastix really holds hot metals. It's made with a superior adhesive that's non-staining and permanently flexible. Use it to provide an excellent seal around windows, doors, roof vents, stacks, access doors, and other penetration points...wherever you need to seal metal to metal.
