Normal pre-paint prep - sanding, cleaning etc.
Very quickly after the last pass of abrasives, spray with zinc chromate to provide a seal and bonding surface for the topcoats. This is essential as it is the only thing I know of that sticks to aluminium. It is the chartreuse coloured stuff you see on aircraft internal surfaces and on Whale gusher aluminium pumps. This step must be done right away as aluminium oxidizes extremely quickly.
Paint as per usual when the zinc chromate is dry.
I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.
