Rotor Hat Refinishing

Seattle-ish, WA
Looks good. Will the zinc hold up better than some high temp paint?

Oh, absolutely.

Around here many use it instead of much more expensive prop and shaft treatments for boats left in the water (yachts, etc.). This is in saltwater in Puget Sound. I did my front rotors with this just a few weeks ago and will do the rear soon. I used the Rustoleum brand I got from Lowe's.
Please report back in the spring. I’m curious If will last. I used this primer on a galvanized boat trailer fender and have most of a can left.
