I have used similar material for RP, but by Dazian instead. You get more of a hot spot the more you stretch it. I like using something like this when I don't have access to a good RP material or I need something that fits in somewhere where I wouldn't want to use good material. You should be able to request a sample (there may be some cost associated depending on the size). That way you can see for yourself before investing in a large piece.
