I now realise why its such a bad thing to leave salt on the car!!!

Wheels ruined salt has got into refurbed paint and blistered on all 4 wheels!!

But worst of all....
The aluiminium strip on the boot lid is fucked!!
Covered in small blisters under the matt finish..i assume salt "eating" into the matt finish.. ARRRGHHH
Also the surrond on the grill has had the same fate...
God i,m pissed off and i,m usealy very anal about car cleaning and the strip was plastered in wax ete which i thought would prevent this.
Any one else had the same?
Wouldnt care had the boot strip replaced under warranty for the same issue last year..but cars out of warranty now!
Any detailers now how to get rid of these "bubbles"?? very very fine wet and dry maybe?
IDEAS ANYONE???
