I was wondering what I am going to do with some narrower (44" or less) 1.1 ripstop that I picked up a while ago. I thought I was going to use it for a quilt or jacket, but the water repellency was pretty poor. I may just sew it up some how and then try your coating method.

How were the fumes? Was this an outside only project, or can a well ventilated garage work?
