What I've been using since day one is seran Wrap for packing. Like the 3M type. It's about 4"-5" wide and it's really stretchy. I wrap my grip while stretching it and bringing it close to the lip.

I layouts the RPG really good because it copies the ergonomic profile of tube allowing me to get a good hand grip.

To cut it off just stretch and pull and it will cut off while sticking to the grip without the need to use tape to secure the end of wrap to the tube.

Here is what I'm talking about.
Impermeable, so works great as barrier. It's the same thing I use to wrap my arm rest after placing a bib on the rest part.
