Price Paid: $6
Used on polyester thread sewn as a deck seam on marine grade vinyl. Tested uncoated sewn sample and water ran through the seams without hesitation. Dried cover and let sit for 24 hours then coated according to instructions. The cured cover held water with only one or two slow drips in the hundreds of stitches.
I wouldn't use it to make vinyl fabric buckets but to keep water from reaching the seat foam in boat seats this worked very well.
Here's what other sites are saying:
A water-based seam sealer that is odorless, environmentally sound, tougher and more elastic than other traditional seam sealers. Great for all nylon or canvas clothing and gear.
