Was at the dealer yesterday getting an oil change and while waiting asked the service manager about drilling holes for oil spray corrosion protection,he said you shouldnt have to drill holes as acess points for such a procedure are already in place. got home and out of curiosity tried to find these acess points,no luck,i cant see them. guess a trip back to the dealer for some explanation is in order. Anyone else have their car undercoated? what did you do?
