I am in the process of making an aluminum backplate. The way I see it I have three options for finishing: anodizing, clear coating/painting, or nothing. At the moment I am leaning towards leaving the plate uncoated mostly because it is a lot easier. I could anodize it, but it would be a pain and cost more than the plate. I have read a few posts on ScubaBoard about galvanic corrosion on aluminum plates. I doubt it is as significant as some make it sound, but I would like to hear what you all have seen.
Questions:
- How have your aluminum plates held up?
- For those with uncoated plates have you noticed any corrosion?
- Is isolating Steel-Aluminum contact with a rubber washer worthwhile?
Thanks!
