Just received an email from Thayercraft this morning. He's rebuilt the website and all of his fiberglass cloth is available again. Hope it helps.

It's been a long time in the making and is a continual work in progress but here's a link to our new website:

https://www.thayercraft.com

I've been working night and day the last couple of months on this website trying to get some degree of organization and separation of the many types of fiberglass cloth and finishes we have that for the diverse fiberglass cloth market. There's so many types of fiberglass cloth with so many applications it's just mind boggling. My hope with this website is for it to work for everybody from the RC aircraft builder to the silicone rubber coater.
