Update:
Went ahead and sprayed the skates.
I spent time masking up the whole skate taking the blades out just to be on the safe side, making sure every bit i didn't want to get painted didn't get painted or leaked on to.
Then with the finest glass paper i could find went over all the carbon to give the paint something to grab on to.
Wiped the whole skate down with an alcohol wipe, and let dry.
Sprayed 4 thin coats of black gloss.
Then sprayed 1 finishing coat really smoothly on the skate.
left to dry for 8 hours
