Absolutely, hot dipped is far the best way to protect steel, any closed box sections like side protection bars should be drilled in several places (in a discreet area) prior to hot dip galvanising to allow the zinc to flow through and coat the inside and to prevent heat/air pressure from warping it.
My Dad has a boat trailer he designed and had built in 1982 in the back garden that was hot dip galvanised - still looks new today.
Yeah its not so good for small parts, but for protection bars and roof racks on a 4x4 its by far the best process.
