HI There
I just painted my callipers last week. – What a job! I was going to use Hammerite paint but having spoken to the manufacturers, I decided against it. It appears that the main advantage of Hammerite is that it does not need a primer and can be used on rusted or other damaged surfaces without much preparation. The downsides are that it is not a heat resisting paint and the lacquer should not be applied until the full curing process, i.e. 6 weeks. From my understanding, if an additional coat of paint or lacquer is put on before the full curing process, the gloss finish will be dulled.
In the end, I used Halfords Heat resisting engine paint, with an oil based lacquer over the calliper stickers. It took me four days to complete.
Day 1 – Clean and power wash the callipers THOROUGHLY. Allow to dry
Day 2 – 1st coat of paint
Day 3 – 2nd coat of paint
Day 4 - Apply calliper stickers and lacquer
Day 5 – Stand back and admire !!!!!!!!!!
Hope that helps. Any questions, let me know.
