I went down to acura for an estimate on painting my greddy lip to pwp, the guy said he might need a sample off my car if i was just gunna drop off the lip there for them to paint, he suggested that i take off the fuel door and leave it with them along with the lip, so they could match the color more accuratly. is this really neccessary? this is my first time getting a part painted so i dont kno how things are suposed to work but i dont really wanna drive around with no fuel door for a day or two, would it be okay to just tell them to match it with nothing since it IS the acura body shop and they SHOULD be able to match pwp pretty accuratly without a sample right?
