| two things ..... if the scratch is in the lacquer and your brave you can make it vanish quite easily.
Get some 2000 grit wet and dry paper, this will feel almost like writting paper. Use a small piece, wet it and the paint work and slowly "rub out" the scratch. Keep to a small patch and don't go crazy. Sounds drastic and looks drastic but works very very well.
Keep the paper wet, only rub lightly and stop every 30 seconds or so to check on progress. Don't press too hard and stop before you cut through the paint work. The scratch will rub out but you will be left with a dull patch of paint work.
T-cut or similar with a soft cloth will put the shine back in, then seal it with polish or similar.
I have done this a number of times on my own bikes and cars to great success. |
