I know I"m going to use 3M, I just didn't know which grade. I also didn't want to waste $7 on a can for one spray. I guess my main reason for posting is to see if anyone else had used a material with no backing.
As far as what I paid for...it's not cheap stuff. I found similar genuine Coutre Ultrasuede between $60 to $80/yd. This is not $6/yd microfiber that I got from Joann's fabrics.
