Welding Blankets

There is a fire retardant spray that can be had from Home Depot, get a wool blanket & spray both sides a lot. I have 2 that I've had for years, I think I used 3 bottles each on both blankets. The one time I should have used one, I didn't have it. My Kirkey racing seat cover ended up with a 4" hole in it before I realized a stray had hit it. LOL
