I am a 1 man band, fabricator of railings, mostly ornamenatl. Virtually all are powdered. I've had very good luck in harsh environments and have a nice set I just added to afetr 2 years and they are holding up great. A couple tricks the pc guy uses; all are zinc primered (powder)before finish coat. They must be sandblasted and perfectly clean prior to coating. ALL joints must be welded 100%. If there are acute angles or similar tight spots or overlaps heat the entire piece first and the powder will slump into them better. These angles are subject to a phenoenon similar to arc blow. On real tight angles (like a basket twist) you can dob a bit of paint into the joint by hand if you can match a color or just a clear lacquer will work well. The only other real problem is minor uncoated spots on holes the rails are hung from for coating and you can clear lacquer them as well. Stainless steel washers with attached sealing washers will help there too.
