Canvas and zippers

[MarcJ]

My canvas is getting old and the zippers are getting harder to zip and unzip. Is there any product that would make the zippers easy to use?

Paraffin wax, Chap Stick, Vasoline, Zipper Ease. You pick it.

Thanks Steve.

I started using Zipper Ease once a year when my canvas was brand new. I never had any zipper problems for 10 yrs! Since your sipper are already old, I'd use the stuff once a month now.
