Rodie Rodewald is one. The air is literally heavy with salt spray all the time and Rodie has found exposed aluminum parts, not anodized, will corrode. He strongly recommends anodizing and insists that it is easy and fun to do. A lead plate a little larger than the parts to be anodized. Pure, soft aluminum wire.
Cleanliness is very important to success.
Heat TSP to boiling, cool to just under boiling, immerse parts 3 minutes. Water rinse avoiding touching the parts. Negative lead to lead plate. Use the aluminum wire. A good contact is the secret to success.
