I need to make a 1 inch cut in a rubber grommet at the firewall of the car to pass through the power cable. That's the only extent of my cutting. Will this give the dealer an excuse not to provide warranty service on the car? I have some minor A/C and hardware work that I'd like to have looked at under warranty sometime.
