When washing the car at the weekend, I noticed that lacquer on one side of my front bumper has started to blister and has peeled in one or two places! It's pretty tough to see but the camera picked it up nicely in the sun.
The car has only covered 12k miles of which I've only done just over 2k. It was bought from Park Lane and was ex BMW management. I'm really fussy about my cars so went over every inch of it under UV light when I picked it up from the dealer and there literally wasn't a mark on it.
Is is common for BMW to re-paint areas prone to stone chips before resale? (I know this is very common for Porsche dealers)
Since the car is still under warranty, will this be covered?
Really want to be aware of my options and any objections before I contact the dealer.
