Review on 🔧 LLPT White Butyl Tape 4” x 50 Feet - RV Roof Patch and Sealant | Strong Weatherproofing | Window, Vent, Camper, Boat Leak Repair | Curling Resistant | RV Rubber Sealing Tape (SV504) by Brian Diaz

I used it to seal the screw holes in the corners of my mobile home. It has shrunk a lot, in some places by more than an inch. Best used only on very flat, clean, dry surfaces with no cracks or holes and allow more than two inches of sunlight overlap where there is never wind. It's good for about a week. It may be better to completely cover it with a very thick layer of rubber sealant so that it will never be exposed to the sun, water or weather, blisters or curls. It leaves a dry brown crust when torn off and compressed.
