I abandoned idea to paint them, because I may go for MPBK (in far future due to limited funds for now lol). However, I read about BMW M3 Frozen Edition (limited production of 25 cars) and guess what BMW did with their oem CAST calipers
Yep, this pretty much sums this thread up: painting calipers red is NOT rice and if anyone thinks so - you guys are living in the past - when Fast'n'Furious 1 just came out and Honda Civic was considered tits
Of course quality of paint job has to be good with good sanding prep etc
