Hi Neil....on my old monster, dremel'd all the loose paint of the fins, degreased, and (after masking thoroughly!!) dusted the heads with a can of normal silver spray paint (black was OK) - trick here is not to apply too much.
Lasts well and really improves the look of things ! Here s a pic of it finished (I did get the side casings and hangers professionally painted after stripping them myself, but my mate has just done his M900 himself with nitromors and smoothrite..see link ror UKMOC below).
