Before you shoot people down in flames, take the opportunity to find out where they are from. I believe he is from the Netherlands, his English is better than your dutch i wager.
Imperial Blue as its known in the UK, is really no worse than most other colours, however it uses a lighter undercoat than many of the other colours, and any small chips show up a lot more.
Not a great deal you can do unfortunately, modern paints lack the hardness of lead based paints, and stone chips are a fact of life.
Using a product like Armourfend that is placed in the most vunerable areas can
help prevent chips.
