I am going to put a bull bar and some auxiliary lighting on my new Ford Explorer. Not only does the black powder coated one look better than the polished stainless steel one for my color Explorer, it is also less expensive too. Here's the deal though. The SS one would be relatively easy to maintain and has a lifetime warranty. I think the black one has a 3 or 4 year warranty and I have seen powder coating eventually flake off things like lawn furniture, etc. Does anyone recommend an especially good care technique and/or product for making the finish last as long as possible? Thanks in advance for your advice.
