It waterproof’s really well. It does go on thick and makes fabric heavy though. That said, I would rather have a thick waterproofer that works than stinky starbrite that doesn’t.
Ted Channing –
The label is just awesome. Miami vice!

I am super happy with this product! No toxins and it works great! I originally ordered the quart, used it all, and then came back for the gallon. I use it on the canvas I use to make bivy sacks.

The 12-volt cord is a little short for my helm but I got it to work alright. Never seen something quite like it but it does work. Ingenious really.

They aren’t kidding about it being durable. I used some to slick up my block and tackle and it is still going strong a month later. Somehow it works better than grease. My fabric is waterproof too.
