Defective panel on 720s

So my dealer says I have a defective panel due to some corrosive defect and that McLaren will replace entire panel with brand new and paint to match. Anyone ever hear of this? Is this normal? They said it's a known problem that does happen. What do you think?

 

Right front quarter panel. There removing entire panel replacing with new and repainting to spec. I'm a little nervous but dealer said it's not an issue or will it effect car value. Mclaren even willing to compensate for not being able to drive since they sent wrong panel 1st time. What do you think?

 

Sorry. The 1st panel they sent was for 720 spider. Apparently there different, so now I have to wait for another panel to be sent from McLaren to get repainted and installed. I guess they do have some known issues and it's covered under warranty.

 

I agree. Just wanted to make sure this wasn't bs. I've never heard of this and was concerned about resale. They lose enough already. I'm very ocd so I hope they match everything.
