mikey,
ugh, sometimes if you want something done right, you got to do with them. i had issues with my install and they've done it before. i ended up coming up with the plan on installing and did it with him. if your not happy with it, then you want to do it again. i know it's going to bother you.
you can try this other type that i was referring to from
www.stickercity.com, they have the vinyl that you don't need liquid and you can crumble it and reuse it. now it's not as UV protect-ant as your standard, but it should hold up fine. give them a call and inquire. they also have a how to video and it will surprise you how much easier it is to work with. all you'll need is one, maybe two other people to help.
let me know if you have any questions?
Later!
Jimmy
