Coil Spring Paint?
 

I did some searching and haven't been able to come up with anything. Is there paint that will hold up to the continual flexing for the springs, I know powder coating would probably be the best option but that's out of my budget. Any input would be welcome!

I agree that powder coating would be the best, but an acrylic based paint would probably be the next best/flexible paint (powder coating uses acrylic based materials as well).
