That _does_ look like neat stuff.
After a spiffy polish job, a coat of good wax on non-high temp parts (like cam covers and such) will dull the sheen just a bit, but will slow oxidation and keep dirt, bugs and small animal parts from sticking quite as readily.
Nothing like an ex-June Bug (or stray cat) - when the last thing that went though its mind was your freshly polished dyno cover... :sick:
