This is the first time I used Mothers Mag and Aluminum polish, wow. You can really see the difference a little elbow grease makes. Here's stages of polishing listed:
Bottom Left: Untouched
Top Left: Scrubbed with steel wool and engine degreaser
Top Right: 1st round of polish
Bottom Right: 2 round of polish.
I start of scrubbing each valve with steel wool and engine degreaser, followed by a round of polishing by hand with Mothers Mag & Aluminum polish. I then follow through once more polishing & buffing with a variable speed rotary tool.
You can really tell which valve covers were facing forwards, taking 47 years of road abuse consisting of every little thing imaginable being shot at it.
A little polish goes a long way. I used Mother's Mag & Aluminum polish. Works great on the raw aluminum, such as carbs or valve covers, etc. It won't really do anything for chrome. The directions actual state
not to use it on chrome. Naturally these aren't perfect again, but certainly significantly better looking. The only downside is the polishing really brings out any imperfections. Such as numerous signs of the previous owner laying down the bike, but failing to ever mention it.
I purchased a nice variable speed rotary tool for all of this, but I found myself quickly reverting to hand polishing for the majority of "larger" work.
You'll see I left the carbs alone. I've seen other people polish them on here, which is fine for their projects, but I'm just not really a fan of that look. Something just strikes me odd see carbs that appear to be chromed.
I tried to clean up the valve cover a bit, but
MAN was that thing
tough. I'm not really sure the best way to go about it sans sand blaster. It make me sure I'd rather just paint the engine case. Though I imagine I'd still have to clean it really well to do so anyway. Really not looking forward to all of that.
