Some red or blue or purple annodized paint might look good on chrome- a light coat that would still look real "anno"- maybe some clear coat over it- i think they even have torquoise at auto stores. The gold is not like anno but like gold leaf.
the paint really works well on chrome, because it's semi-transparent and goes too dark to look anno otherwise, but I've also put it over "chrome' paint, and it looks pretty good-but real chrome is better- in fact the best for metal "anno" paint.
I might do it on something chrome that was starting to wear or peek rust- it would protect it.
$5 at Wal-Marts- was closed out but seems back- more colors and more money at auto stores.
I've painted both my motors, although I had the same overheat worries at first- now they even have internal sound dampeners and I haven't had any problems here in hot Florida.
