Ok... I'm mainly a screen printing guy but just barely getting into vinyl.. my suggestion is to test for yourself. Wash it, dry it, try and peel it off, stretch it... 100 people could come on here and tell you what you should do but that still may not work for you. Still listen to the opinions, and hopefully someone will give you some that knows more then me, but then it's up to you to test it to make sure it's a quality product
Do a sample, wash and dry it, then try and peel it off... if it pulls easy you'll probably have a problem... if it won't come off that easy then your probably fine..
Thanks,
Jeron
