So I purchased some 70D Calendared Ripstop from MagnaFabrics at a great price. $1.25 per yard. I bought the Foliage green, which turned out to be the perfect shade, should blend in with forest perfectly. It comes with a Water based DWR coating on it already. (I had to call and ask what type of DWR it was and Larry was kind enough to track down the manufacturer and find out for me.)
Anyways, my question is; Will a Silicone water proofing Spray, like shown below, stick to the already Treated Water Based DWR 70D Calendared Fabric? Or will it just peel back off?
