Guys, guys, guys,.... seriously, UHMW tape is going to turn to garbage PDQ. It yellows, won't come off in a nice piece after it ages, and generally looks like **** from day 1.
You need paint protection film like they use on the front of BMW's, Mercedes, etc. You can order an expensive 120' roll of your own, or simply buy it by the foot from us. You won't be sorry. It isn't expensive and it looks great, lasts forever, and can be removed up to 10 years later without leaving a gooey mess.... I know I've had it on my plane for that long!
It's stretchy enough to go around curves, easy to cut, easy to apply, and won't yellow... I said it WON'T YELLOW... ever.
I have it under my gear leg fairings, around the cowl, on top of my flaps, behind my keychain on the panel, and, yes, under my canopy ducktail. There are literally a 100 uses on any RV.
We carry it in 2", 4", and 6" widths.
