Good on you Bill for wanting a have a go at this, nothing more rewarding than doing it yourself.

Can't wait for your pics.

Having said that, I hated the maintenance of polished alloy after one manifold I had done a few years ago.
Cost me $60, looked like a mirror on day one, but I just couldn't keep it like that.
If I did it again, I'd go for a chrome plated finish.
