T6.1 sliding door

Hi, polished van the other day and noticed afterwards under the window on the sliding door the metal looks a little rippled compared to the rest of the van. Is it different material? Any one else notice little imperfections?

This is a brand new van i should have mentioned that. It seems when I’ve looked at a few camper van conversions the sliding doors have a few imperfections in them compared to the rear quarter and front drivers door. Thought the sliding door may of just been made from lighter metal etc. Think im probably being too fussy and looking at it like a car body.
