I'll offer my snow belt comment again. If you live in an area where snow/ice melt chemicals are used and you ever intend to drive in the winter when roads may be treated you may want to think hard before using powder coating. It is a thin film with very little flex, and if you get any flaw like a rock chip, scratch, gap at a inside corner, etc, that lets moisture in your frame will rust beneath the coating and you may not know it until the damage is extensive. It is interesting (to me) that everyone high on powder coating is in a sun belt area with little or no snow threat.
