Given this is a car... and that Lotus anticipate that it could be damaged (including scratched)... there is actually a definition of acceptable damage in the service manual. The chassis is considered serviceable as long as any damage to the chassis is not "significant bending, tearing or distortion" and that the correct alignment can be achieved by the standard range of adjustment. Minor cosmetic damage is repairable.Look...had this chassis been made of mild steel, it would have been perfectly acceptable. There's your, awe, gee...we tried our best...
On that basis I am confident, as is Daniel (clearly), that those scratches are not structurally damaging.
Honestly you could be the worlds greatest aircraft structural engineer and materials scientist... you could even be right in this case!!!!!!A significant amount of my aircraft structural repairs are from photographs... try to justify it as you like. I'd still love to pay his life insurance policy.
But sadly the arrogant way in which you conduct yourself on this forum - combined with multiple times where your opinion has been called into question by well respected experts on this forum - means that no one takes any notice of what you say.
I believe I have suggested in the past that you think and read more and post less... please give this some serious consideration.
