Looking for advice to repair a minor cosmetic detail if possible.
I have an Elise Cup 250 and have noticed a small (half inch) scratch in the front splitter, maybe from a stone chip or something. Luckily it isn't too dramatic or visible unless you are looking at the car from low down, but it has gone a silvery colour and would be good to make it black, smooth and invisible again.
It is a regular splitter, not upgraded to carbon fibre or anything, just the plain black.
What is the best product for me to use to repair it, or should it be done professionally?
