So I got what I thought was a pretty decent deal for undercoat and rust proof, as well as some paint protection and sound proofing when I picked up my 2010 sedan.
Now doing some research (which i should have done first) I figure I should have passed and just gone to crown. That being said, would it be worth while to get the rust proof done at krown as well? Would it void my warranty on what the dealer did? Anyone got an idea?
