I agree with the assessment of galvanizing. I work for a design build contractor and we send all of our steel, subject to the outside climant, to be galvanized. It is extremely durable and fairly cheep if you have a large amount of weight to dip. We send truck loads of steel down. If I ever go the full on rebiuld I will have my frame dipped also. Word of caution though, never send anything that is hollow but sealed such as a drive shaft! If dipped it would explode and the dipper will not hesitate to torch a very ugly hole in it.
