So BMW is the rootcause
Anyway I went to PDR today to get the dings fixed. They managed to do the side one with no problem. But the two @ the bonnet, he only managed to get one done. The other was still visible though it became smaller. Reason being our bonnet got double layer so access is limited plus its made of Alu which made it more difficult to retain the original shape.
The guy was quite upfront as he told me no promise from the start. Also saw him turnaway another car (also bonnet) as he said even if he can do it, it won't be back to original.
