I have to admit that the stone chips are rather concerning. When I had my kit fitted a few weeks ago, I pointed out some bubbling on my bonnet near the mesh. This was quickly dismissed by my dealer (Leicester) as "stone chips that have gone too deep into the paint work and YOU haven't touched them up therefore they have started to rust..."
I wasn't best pleased. So after a number of discussions, I found out they have Chips Away on site Monday through Wednesday and for £15 they will sort all the chips and rust out on your bonnet in two hours. I obviously negotiated that I ought to get this free... Its booked in in two weeks!
