Canvas Slide Topper Treatment?

[SpaceNorman]

Anybody ever apply any sort of treatment to the fabric of their slide toppers? I was just looking at mine today - and while the fabric is 100% intact (no fraying, no rips, etc.) - they're obviously weathered and don't show any evidence of any sort of waterproofing on them.

As I look at them - I can't tell if it whatever waterproofing may have been on them original has simply weathered away - or if there was never anything there in the first place.

Has anybody applied any sort of waterproofing treatment to their slide toppers? If so - what have you used?

Not really a water proofing but spray 3M Scotchguard exterior with UV protectant on the awning fabric.

The most highly recommended product by professionals is 303 Fabric Guard.

Many toppers are vinyl, so not much to do with them. They are waterprrof as lng as the vinyl is intact.

If woven fabric, they may be Sunbrella, some sort of canvas, or a woven acrylic fabric. Most any of the woven ones can benefit from something like 303 Fabric Guard, and the material was treated at the factory when it was made. If they aren't leaking yet, no worries.

However, if your concern is cosmetic, you need to get them clean first. Coating over dirt just makes the dirt waterproof.

West Marine has canvas water proofing in one gallon container. I use a simple garden strayer to treat my toppers. It just keeps,the water from seeping through the fabric onto the top of the slide.
