Ehehehe,
I think the same way Chris thinks. I personally know nothing about mechanic or body work but I have the guts to stick fiber glass on to my cars body and hope it looks good. Think about it this way, if you screw up when modifying something on the cars body, it can always be fixed somehow (Don't burn the vehicule doh!

).
It's all about balls and thinking! :p
That's my opinion!
