Cast manifold query

[Mad4slalom]

Hi, I have the cast Ram’s Horn cast exhaust manifolds on my 72.
the original owner had a grey ish finish of some sort applied during the restoration. Just wondered what, if anything folk put on theirs to keep them looking good, had used zeebrite grate polish on black m/cycle downpipes back in the day , any suggestions welcome. Thanks all

This is what I use. Calyx . It's a grey silver metallic paste, don't need much, old rag & then buff a bit when dry.

Thanks for swift response. Is it an automotive or household product? Where should I look to buy some?

It's automotive. Don't need much lasts ages. Available in UK from Frost's, but pricey, £37

Can get from the US, EBay.com it's £14 but shipping a lot. There is a listing from an individual seller but need to request shipping cost. He may post it US mail, meaning no FedEx charges & it's below the tax threshold I believe.

I painted my cast iron manifolds with POR 15 High Temp Factory manifold grey available from Frosts . Needs good surface preparation and applied in the recommended ambient temperature conditions but works well and I think still looks pretty good after two years . Definitely do not use the cheapo stuff such as available at Halfords etc . Not nearly the same quality or high temp rating .
