i had thought i finished a new holland hit&miss . which i clear coated the outer ring and flat surface of the flywheel with plasicoat clear from a spray can which looked good. but after it was siting around now for about 3 months after i put the clear on i am showing rust under the clear coat. the material is cast iron on the flywheel which i sanded to get the finish i was wanting. and was very careful not to touch it with my fingers , but i did wipe the surface down with thinner to get the sanding dust off. and let it dry for maybe 15 min. then i sprayed it on my lathe while spinning at a slow rpm. and let the clear dry for a day then resanded lightly with 600 grit. cleaned as before and then recoated again.which when that dried i put the third coat on.but now there is rust starting to show under the clear coat.
the flywheel was powder coated for the main center section. which was heated to at least 400 degrees for that process. so all the moisture should have been dried out of the casting.
if i strip off the clear coat and polish the metal again what can i do to stop this from happening again?
was the problem the brand of clear or what?
