CJ, let’s remember, we own cars that are likely insured as antiques, but (at least in my case) are younger than us... I have every document on my car going back to the original sticker...every year’s expense summarized with supporting receipts (including gas purchases) during the car’s 38 yr tenure as the first owner’s daily driver. This even included the accident report from a fender bender.
Despite this, the original owner (my penpal of 15 years since I purchased the car) doesn’t recall another “bondo incident” discovered and repaired in my recent 4 yr long restoration project. We all aspire to perfection in these things, but it’s a needle in a haystack.
BTW, are you pulling the body off for the paint job?
