I have a Surly Pacer I picked up second hand. I believe a small chip in the paint on the downtube of the frame may have occurred from transporting the bicycle on my roof rack, or perhaps from a ride (really not sure). I emailed the manufacturer, but was curious as to what solutions you guys might suggest. My friend thought I could get the paint codes from Surly, and cover a touchup paint spot with clear nail polish, like a clearcoat. But honestly, how many different types of black paint could there be?
