as i said, a few days ago i took my callipers off to do a refurb...i took them off soaked them in hot water mixed with fairy to loosen the dirt off. What i noticed was that the callipers had no laquer on them, maybe due to the heat that goes through them but anyway after cleaning them i was not too fond of the red paint match, so instead just laquered them using high temp paint 
this shows how dirty they were, i soaked them both, rubbed the dirt off one....
