Well this winter was stupid hard on my truck. All 4fender corners which take the spray of the tires are wore right to bare metal plus my black truck's bottom from the molding down looks like salt and pepper. What do you guys use for "touch ups" on chips that are larger than the bottom of a coke can? I was going to use the GM chip repair brush but I would neeed 4-5 of them. Body needs to last 2 more years then getting a full repaint. The body is taking a shit kicking at School everyday so body work right now is pointless.
