Another reason we went with Jackson, they use galvaneal steel and
undercoat the roof and fenders. They also use Sherman-Williams
automotive paint in a five step process:
1) acid bath
2) Prime with vinal wash primer
3)All seams are sealed with rubber seam sealer
4) Then it is again primed entirely
5) Application of at least 4 layers of Acrylic Urethane Enamel
so far, so good.....not a trace of rust (unlike the Bonanza I might add)
tracy
