I have my tint coming in the mail soon and I took off the nasty looking carmax stickers on the back of the car and on the side window. The stickers left a lot of nasty goo that I can't seem to get off. Is there any solvent that I can put so I can't get this stuff off with ease without hurting the paint? Thanks.

 

Goo-gone or lacquer thinner...mineral spirits.

 

WD-40 and a razor blade will work very well for that sort of problem. Just be sure to lay down a cloth on your speaker deck or dash so you don't get oily spots should it drip down.
