this is where the saying "you get what you pay for" comes into play.

while it sounds like you're getting a good deal, these special "hook-up" or whatever deals usually turn sour as soon as the customer (you) realizes that the friend that's doing the work does something against your liking. you show your dissatisfaction, and he'll stop working on your car, or something worse.

i've read plenty of these stories all over the internet where someone thinks they're getting a good deal on some body work and in the end they have to pay some professional to correct the work.

my suggestion is that you dont do it at all..
