Thanks for the replies!
I have no idea how to sand a car. I'll have to look it up.
Josh touched on my question about sending the car back a little, but I'd like more information on this subject. Specifically, I want to know if it will fly if I see blemishes or something and tell them to fix it. Will they do it? For free? Kinda like sending back a pizza with the wrong toppings, haha.
