Finally got round to painting my calipers today.
don't know about down here - but in the UK, the IS calipers have a real problem with corrision.
heres a pic of mine before I painted them
as you can see, they look really awful, with white, fungal looking spots.
Got the wheels off, and gave them a good scrub with a wire brush to remove any rust or flakiness.
Them rubbed them down with white spirits to thoroughly clean the surface.
Gave it two good coats of Hammerite Smooth - was a beautiful warm day, so it was drying nice and quick - left it for twenty minutes for cold drinks between coats.
Left it to dry for half an hour - and put the wheels back on.
big improvemment I think!
I have some chrome Lexus stickers to go on them - but thats a job for next weekend :(
