Been thinkin' 'bout rust issue on this one..need to revise my comments now that I know it's in AZ.....that orange stuff could be from the orangish dirt in the AZ area.....not all rust. My undercarriage (and most other areas too) is always covered with an orangish coating....this may not have as much rust as I first opined...
'Course I don't know where it's been for the last 10 yrs, but the coloration I see in the pics, makes me think it's more AZ dirt than rust....just my 2 cents...
Luna what do you think?
