Yep, Holds up fine and you can wet apply it.
I have wet applied the GF vinyls for years with no issues. Yard signs, magnets, window decals ect.
The economy grade vinyls in most vendor companies anymore are avery or general formulations just rebranded. It sounds like it's one of the GF vinyls because they have a economy grade vinyl with a grey adhesive.
For cheapo print/cut stickers you can't beat the economy grade vinyls, yeah they shrink over the course of a few months but nobody is going to pay a premium for some promotional stickers and these still do hold up just fine. I switched to 3165ra recently for all my stuff though, It's not much more, shrinks less and lays down better.
