Sandblasting vs other forms of restoration.
I just picked up my 1971 25' Airstream and am fairly certain the frame is in great need of repair. It was previous located in South Florida, so exposed to a lot of moisture and salty air. It seems to be pretty rusty, but hopefully no worse.
I'm considering having it professionally treated, as I want to ensure the frame is safe! I've only heard of sandblasting, but just yesterday heard there are other, newer (maybe better?) blasting forms.
Does anyone have insight on sandblasting? Other blasting? General advice during the frame repair process?
