Leave it be, unless the paint job gets totally wrecked at some point. It's a great color and the pin striping is really nice.
I built-up a 79 frame I obtained, which had a fair share of chips and scratches. It has gotten more over the years.
I just keep touching it up. Model Master Burgundy Red Metallic is a pretty close match.
The paint job is prone to scratching because its on top of the polished chrome.
