I had painted mine a- two tone - one for the cradle, the other for the piston housing - but watch out for rocks and road hazards - because they will beat up your paint job. Brake dust adds to this too - so if you race a lot - the cleaning off and the eventual "stain and discoloration" you get from the Heat cool cycle's takes their toll - high heat paints work but they too can chip.
IMO - to me Ceramics are overrated - they require a prep that if not done right over an annual phase of times - it' may be easier to just remove-pull off and throw out the old painted assembly and put on a new one - then start over - layering on as possible.
The seals don't take too kindly to stripping solvents like ketones in solvents like MEK or Toluene - might as well sandblast it off then repaint - again a seal issue.
Even a "durable" like ceramics' claims to be, they only last as long as the road and lifestyle you live - let's them look like they do - as long as they can survive it..
Some people never get off the street and onto the country roads, so obviously a good paint wears longer - it's when you go off roading or onto the track does the paint job show how good it got put on. Good surface prep is a must - washing it off with a good solvent to remove the loose rust - it's a pull off and detail-it sort of thing so there is some assembly and bleeding that has to happen for the process - and the errors of assembly show up if you're not careful. So do the job, right, and you won't crash it.
