Waterproofing my Jayco Pop Up

[adwizard]

Hi, I own a 1992 Jayco 1006 pop up camper. Although I don't get any leaks in my camper I have noticed that certain areas of my canvas get saturated and no longer repel water from rain. I have read about many types of waterproofing products, spray on, brush on, etc -- and many come with mixed results. Can anyone recommend a good product that I can apply by brush on my canvas. I believe this Jayco camper is made with 100% cotton duck canvas. Any suggestions or recommendations? Jayco recommends scotchguard but that just adds a thin top layer and not long lasting results. Thanks.

This product works great a friend used it on an older popup it soaks into the cotton duck canvas and made it waterproof for many years. https://www.montanacanvas.com/produc...s-preservative

We have a 1998 Eagle 8SD with similar cotton canvas. We've had good luck using 303 Fabric Guard. I sprayed it on, but instructions also mention use of a brush or roller. Fairly expensive stuff, so shop around:
