don't even think about it lol when I ordered some January of 2018 to test, I didn't get to it for about a month. It shrunk about 1/8th inch all around from the liner. hazy, orange peel etc. don't waste your time efforts and money.
At work, for the past 3 years, we’ve used 3M scotchguard with J&J baby soap. I always prefer my solution a little soapier and as far as making it stick, we use straight vinegar.
