Butyl Sealant Tape

This pliable non-hardening butyl mastic is a superior replacement for the original non-butyl putty tape used on vintage travel trailers. Unlike old fashioned putty tape, it does not harden over time. Also, it is safe for contact with EPDM rubber roofs because it does not leave petroleum
It is used when installing moldings, windows, doors and vents. It waterproofs overlapping metal and seals around fasteners when they are inserted through the tape.
Can be trimmed to width.
