:woo: Nice one - Sounds like you’ve got one of the "helpful" dealers at hand!
Not convinced about the lacquering idea though? :eusa_think:
For any lacquer to do its job properly you'll need to get every last bit of zinc oxidation off the surface of the spokes; the zinc coating (galvanising) will need to be shiny, pure zinc, not dull oxidised zinc. It is also normal practice to mordant wash (with something like
this) and etch-prime galvanised surfaces before coating in order to get it to adhere. Trouble is etch-primer will be a solid colour, so hopeless if you want a clear coat natural finish and the mordant wash turns galvanising black! Certainly, as a minimum, treat them to a rub down before applying any coating.
Trouble with putting lacquer on is that if there is the tiniest blemish in the coating (or it gets chipped later), moisture will inevitably get in, the zinc galvanising will start oxidising and the lacquer will lift. You may possibly end up with something looking worse than if left alone in the long run, which would be a real bummer if you’d spent hours prepping and coating the spokes!
A thin film of Vaseline, grease, ACF50, chainsaw oil (or some such thing) would be the easiest, cheapest and most effective preventative measure. If you want/like shiny spokes, then sadly there is no substitute for stainless.
