ok i guess its time to give my 2 cents!

i say take it off.
as much as i like vinal.................. its cool on windows, but im not realy a fan of putting it on paint.
#1 it can be hard to get off
#2 if you leave it on for any real langth of time you will notice a difference in the paint after getting it off.

ive see a few cars and trucks the had vinal remover and the paint was noticabley different under the vinal.
my brothers truck is a good example, he had racing stripes on it when he got it and he decided to take them off (alot of hard wook, inch by inch) and now you can still see were they were becuase the paint is muck nicer looking were they were.

it all realy comes down to what you like.
a little splash of the right vinal lay out can work wonders for the overall look of a car.

Heck, most folks have THAT many colors on their license plates David...

^ True, but that's not something most people can change.

thanks for all the input
for now its a keeper
thanks again!!!!!
