I LOVE Arizona!

Well, there's a flip side to your statement G.T.

.

True, the sheet metal and frames are usually rust-free. As having been a Engine Machinist since '84 starting in Cleveland, and then continuing from '93 here in PHX, I will state this. Many classic engines (or any for that matter) here in AZ are suffering from severe internal corrosion problems more so than engines back East.

Back in the Snow Belt, you need to use antifreeze (that usually contains a corrosion inhibitor), here in AZ folks just stick the garden hose in the radiator and fill'er up. There are a LOT of corrosive minerals in the H2O her for some reason. They attack aluminum (and iron/steel to a lesser degree) and it spreads like cancer. The most common failures I've seen are head gasket failures where a coolant passage ate through the fire-ring of the gasket and pumped coolant into the cylinder.

Fixing this damage is possible, but what about the internal passages you can't aggressively grind out and re-weld ??? We had an Old Boy that Loved Flathead Ford engines for his Hot Rods. I can't re-state how many cores he would haul in, and we would reject because the iron blocks were severely corroded into the exhaust passages. He ended up finding a warehouse in France that had NOS blocks for generators that were WWII era.

Used cars here in AZ CAN be a ticking bomb since some folks can be cheap skates on maintenance issues.
