FWIW i gave Jay Leno's Fabric Seal a try on my convertable top. I'm in the process to replace my top shortly so I gave this a test and was actually impressed somewhat. I previously used Ragg Topp. but these intial results with on coat is sort of impressive. Probably needs a second coat. Would take at least 2 bottals for first application to work better.
I'll keep the old top once replace and test on it a little more.
My top is prertty much worn out and distress so I gave it a try, Don't know if others have tried it and how long it will last between applications.
I did a little reseach on his product line and it appears to have a connection with Dodge Direct Connection..

Intial 1 coat with Fabric Shield
