hiya
I use cans of zinc spray when restoring cars, when i spot weld body
panels
together you need a good electrical contact but if you leave the gap paint
free they will rust inside the seam.
The zinc spray can be as much as 99.7% zinc but some are less. The
problem
is painting over the zinc. Paint just doesnt stick very well, as a coating
on its own I would say try it but dont expect it to wear very well .

Would this be worth spraying on the shafts, props and rudders?
I saw this at HD, Zinc galvanizing coating in a spray paint can.
It is $5 per can.

Since it is zinc and cheap It could not hurt right?
