here's the story. recently performed some front end work. placed a hydraulic floor jack under the frame rails to jack the car. hydraulic jack nicked the rust proof claddding a few places on the frame rails. the jack slightly deformed the right frame rail. I'm taking the car to a very reputable body shop to repair the frame rails. they said on the phone that they can spray over the nicks with an underbody coating after the repair is made.

one other issue, on the right frame rail, it appears at some time in the cars life, a tow truck driver used a hook and there is a gash about three inches long and approx 1/2 inch wide. I'm going to ask the body shop if they can effect a repair by welding.

now, for the big question. the car is a 1991 560SEL, as we all know the underbody coating on mercedes is known to get nicks or cracks which allow water in and rust can form. this car does not appear to have any of those issues (YET). I'm thinking of stripping all of the underbody coating off and recoating with either POR 15 or Miracle Paint. OR, should I just let the body shop spray the affected areas and be done with?

I don't think I've ever seen a W123 or W126 that didn't have jacking scars on the frame rails; sounds like you're going above and beyond to even consider repairing them.

I personally wouldn't bother stripping the entire car and re-coating the underside. Is this a concours restoration?:eek: Unless you're really bored, and have alot of time and patience on your hands, well...

As long as they re-coat the repair, you'll be fine. I would get that gash patched up, yes, if only for structural peace of mind.
