Thanks Red.
I assume hamerite paint should do the job.
Hey John......
If you're about to do this, don't forget the hub area of the discs, they're all too often left and are usually dirty / rusty etc and take away from the overall look
Hammerite smooth silver for the hubs works well, it's what I use and have done for years with no issues, just a great smooth silver stock looking finish
Re cleaning / sand blasting calipers etc.
Unless they're in extremely bad shape sand blasting won't be necessary. Get them cleaned thoroughly and use of a good wire brush all round, finished with a paint brush to remove any loose debris will be more than sufficient.
Unsure what colour you're considering for the calipers?
Mines came with black originally and I re did them myself using Hammerite smooth black and had excellent results
When I decided to go for red I opted for Ferrari red and bought a small tin of gloss from Ebay giving the results you see using a brush
Longevity is good if cleaned regularly and looked after, I personally though like to freshen mine up once a year in spring and have it down to a fine art, around a little over 3 hours to do all four corners.
