Recently I found a Store here in Las Vegas (XP SIGN SUPPLIES) to buy Vinyl the only thing they have is Avery - Gmi Vinyl so I got some (5 yards) to try can't say I like it much, It is very hard to weed, because the glue strings and lifts everything around it at first it was the blade was not set right but that is not it. Not only that, after it is weeded and taped the graphics and letters will lift if left sitting on a flat table. So I am thinking maybe the vinyl is old or something but it was cheep and no shipping,but if you can't use it what good is that? I am going to try Green Star I don't how good it would be for car windows I have Oracal 651 and that works good.
