It's a good thing you are trying to get that squared away at this time because based on my experience cover life with canvas is abut three years of good service.

I'll check back on here to see if someone has some advice. My only advice is to buy a massive plastic tarp and use that under your cover. Wish I had better advice. Good luck.

Thanks Bob. I really appreciate your reply.

I discovered that brick sealant has siloxane as its principle ingredient, the same as Fabsil and similar products. And this:

Clear Sealer (Siloxane Sealer) | Chemisol

states that it works on canvas. It's flexible, breathable, clear and UV/heat resistant... so I can't see why it wouldn't work.

Maybe I'll be the guinea pig for you all...
