Hey, just thinking, have a rolling shell I’m interested in purchasing, but wondering how one might check it for structural rust, especially the chassis rails. Crawl underneath and tap with a hammer? Poke at suspect spots with a screw driver? (Assuming the seller lets you).
Do the rails rust from the inside (not sure how water gets in) or from the outside?
What / where else would you check a shell, apart from visibly obvious? Datum measurements, maybe, or is that a bit unrealistic.
Don’t want to spend $10, $15k on a shell then find in first two weeks of owning it’s only good for panels and off cuts.
Cheers, Richard
