I'm the process of masking of front brake discs and calipers for blasting, so they can be re-sprayed.

But wondered if, firstly is it best to get them powder coated or sprayed (Using Halford's spray for example)
Secondly how will the heat affect either of these as both conduct a lot of heat especially, say on track days.
will the paint begin to peel after a while or is there some kind of special paint required?
Apologies if this seems a bit of silly and naive question, but thought it best to ask before diving in there.

see bigstinks nc30 restoration he seemed to good result using plastikote gold paint on his disc centres

i know you can buy proper brake painting kits from halfords etc which have paint ideal for brakes as they are designed for high temp. not sure what the colour selection is like though
