I have a set of aluminum stanchion bases that have done a great job of slowly corroding since their inception in 1977. A few hours with the new Dremel tool, and I was able to clean them off nicely. However, I'd like to protect them so I don't need to do this again for a long time. My thought was that since the boat's aluminum toe rails are black, I'd paint the stanchion bases the same flat black. That brings me to my question...
I've seen all kinds of advice for priming and painting aluminum spars, or hulls. The products I see recommended tend to come in quantities that are WAY too much for this little job. I only need about a pint of paint. My stanchion bases also don't take a lot impact abuse, so I'm thinking (hoping?) there may be a more economical yet still effective way to prime and paint them without buying a gallon of something expensive.
My boat is fiberglass, used 100% in fresh water (Lake Ontario), and I'm a weekends-only cruiser (so far!). So, again, I think my demands are less than some of the hull / spar oriented products are designed for. No ocean crossings in my current plans, and I'm not planning to paint any other aluminum in black, so no other places to leverage the purchase.
Has anyone used a Krylon or Rustoleum (or other more widely available paint?) product for small parts like this with any success? Yikes, I hope I won't be flogged for suggesting a non-marine paint
My refit budget is hurting, so I'd prefer throw money where it's not justified. Then again, if I gotta do it, I will. Any thoughts?
