Wow, I didn't even know that the tanks were aluminum. I had to go check.
I'm a rookie at this KJ thing but all the bikes I can ever recall seeing were painted completely, no bare aluminum. Aluminum does need to be roughed up a bit and primed to hold the paint.

the silver on my bike is bare aluminum, probably highly
polished back in the day, was just wondering if the factory
ever shipped them out that has been that way for 70+
years in our was my dad's bike. thanks Juan
