i'll just tell you my idea maybe i can go about it a diff way?
ok i dont wanna have licences plates on my front or back...so im gonna put it in the front window *we have to have 2 in bc* and one in the back window...but in the back window theres not where to just place it lol so what i wanna do it....make some kinda frame in the backwindow so the plate doesnt bang around but have it tilted kinda....and im gonna have tint so im gonna cut a square out of it so u can see the plate but it will be on the inside.....so any other ways i can get it to stay?
i used clear epoxy, from the auto parts. this is why i used it, maybe this will help u.
i broke off my rear view mirror and it took a junk of glass w/ it. i filled it in w/ the clear epoxy, stuck the mirror back on (that had other junk of glass on it) and stuck it in there. its stuck good and has not fallen or anything. very much worth the money.
