    you need to leave them to dry somewhere warm and dry for 8-24 hours after they've been painted. If you don't then the paint won't harden properly. If you've done them outside at this time of year then the splatters are not paint melting, but paint not yet set!!

    Did you use "brake calliper paint" or Hammerite?

    i left them 2 days to set, although it was outside, im thinking an error on my part then, it was a caliper paint, im thinking of striping them back again, would make sense? thanks for the reply, daz

    the heat will cure them so long as it's dry, but at this time of year the relative humidity of the air means they'll take days to fully harden.

    If you used the proper two part caliper paint and that's happening then I suspect you didn't use enough hardener, I painted my calipers on the car on a cold day in winter (outside) and the paint had still hardened enough to reassemble everything in a few hours.

    Will powder coating stand up to the heat generated by the brakes?

    I done mine with caliper paint last Summer and they've been good as gold. Although the red wasn't a great idea as they are a mare to keep clean looking:Flush:

    i think so...why not? powdercoating actually involves heating and baking the powder iirc
