Waterproofing fabric advice

I'm getting a sun canopy shortly to use when we don't need the awning for overnight stops. Being realistic it will be more of a sliding door rain cover, so I'm thinking of treating it with a water proofer. It is quoted as being shower-proof so I guess the rain will run off it to a degree if it's angled right?

Any recommendations as to what to use please?

 

Fabseal is what you would use to re-waterproof tents etc. available in camping shops

Fabsil. Brush it on, let it dry and that's it.

 

What material is it made off?

 

I think the proud to pop ones are vinyl?

 

Give me a shout, I have a box of waterproofing samples under my desk

 

fabsil is excellent!
