The aluminium tank on the bike I'm assembling looks really good as-is. I've had it quite a while, doesn't loose shine. Would be easy to maintain/polish.
But, for this project, is too dominant, too shiny, it makes cylinder head and other castings seem a bit dull. Don't want to take engine apart to vapour blast, as it's low mileage and clean.
Today I 'polished' the stainless steel front mudguard with scotchbrite. So, lost its shiny surface finish, has now a sort of deeper shine. Looks really good.
I want to do the tank too, now. Also would have an advantage of hiding any tiny scratches.
There's the obvious difference in metals. After finishing the mudguard, I cleaned finger prints off with meths. Can't see I'll ever have any problems with the finish.
Might a satin-finish aluminium corrode (atmosphere, it won't be left outside, or ridden in the wet). I won't clear coat it.
Can a brushed aluminium surface be tidied with something like used on crankcase covers, but to clean and even up, not make a mirror-finish?
Aluminium is obviously softer. Would the scotchbrite flap wheel be okay? Not too abrasive?
Will I regret it? 😯
