Hey Dave, thanks for reaching out. Yes, the Alpha Systems Mylar-Backed Butyl Tape for RV Walls # AL26FJ can be trimmed down to size using scissors. If you are cutting it widthwise, I recommend making a clean, straight cut with sharp scissors since the Mylar backing stays permanently bonded to the butyl. Keep in mind that cutting the width removes the factory “no-edge” finish along the side you cut.
What Brinkley model do you have?
