I think the coating that's on the springs, whether paint or powder, will eventually crack off due to stresses. My theory is that the plastidip would hold that chip in place without breaking (perhaps bulging out a bit), thereby protecting the raw metal from the elements. Hopefully, this would hold off corrosion, at least for a while. Again, just my theory.
no because the door and bumper aren't in constant flex.

i think it has to do with holding in moisture for corrosion aswell.

if you're talking about the plastic-dip spray i doubt that would hold up. now if you're talking about the industrial tool dipped type i can not say. it would have to be perfectly clean of any corrosion prior to coating.
it could help some. not sure if it would be worth the effort.
