it doesn't have to be perfectly clear, heck it could even be white. I picked up some "decal paper" at staples a month back or so (10 for $12) and it was static cling decal paper...still havent gotten back there to return it (never opened it once I saw that static cling thing on the package)
I'd like to get it someplace local...
I just need it to print a logo for the battery packs that I sell for micro rs4's, so it doesn't need to be clear or whatever, just vinyl and have really strong adhesive
