Tins refinished in rattle can hi-temp satin black.
I by did my rear main only last 15-17K before leaking? Maybe I’d pushed it in to far (“oh behave!”) and I can’t recall using a sheet of plastic to guide the inner surface as I did this time. Hopefully this one lasts longer.
Re: hardware, without being too pedantic I do try to reuse the factory stuff if it’s in good shape. When I did my suspension overhaul a few years back I sent all the fasteners off for replating but I’m not that energetic now. I clean them on a wire wheel (quite fastidiously) then swish them in WD40.
