The last 2 years I have made sure to have them waxed before I go but it doesn't prevent the spots. I was using automotive wax so not sure if marine wax would make a difference.
Permanent Ceramic Coatings are popular for this. They are expensive and are mostly professionally applied. I've had it on my engines for a years or so now and it certainly is better than nothing (salt on black engines is quite noticeable).
MV Detail in Salem is where I had the stuff applied.
