My 02 MB EXL was hit by something falling off a truck, leaving two small chips in the paint on the hood. On of the chips is clear through to the metal. Also caused dent, similar to hail stone. I'm planning to get dent fixed; in the meantime, should I use touch-up paint on chip (to protect metal) or will this interfere with touch-up job the shop guys will do? Chips are small-1/16th inch
