Hope you are ok after your crash. I had a friend of mine who owns a panelbeating shop make up some paint that matches my bike's colour to use as touch up paint. I then use fine art brushes to build up the paint in successive layers untill it stands proud of the original paint. I then use 1200 grit sandpaper and a lot of water to sand it down to the same level as the original paint. WARNING......BE VERY VERRRYYY VERRRRYYYY CAREFULL>>>>TOO MUCH SANDING WILL TAKE AWAY THE ORIGINAL PAINT!!!!!!!!! The whole area is now dull and I shine it up with LIGHT rubbing of something like Brasso, Silvo or a rubbing compound. Withs some due care you can completely get rid of these ugly marks on your baby.
Hi Sniper X
I did not read your post properly. The little I know about carbon fibre is that scratches are bad news. It causes a place where the material is weak and may fail. Rather have your fork inspected by someone who knows and maybe get a second opinion. You do not want a fork folding at high speed.
