Is this normal for my wheels ?

Got fed up with my wheel nut caps always looking grubby!
      Get a piece of wood, say 6" x 18"  ,buy some ordinary nuts ,I think ther'e 17 or 19mm  and silicone each nut to your wood.
           Pull off wheel caps and place one on each nut, then get a spray can off satin black or colour of your choice !
        You can then easily spray all the caps on your board ,after four hours they will be dry and ready to refit ,and your all kitted up to do them as soon as they get grubby again!!!

The reason the wheel nut covers go like that is from some of the alloy wheel cleaners that some dealers use. Just get some replacements and they will be fine as long as you don't spray them with anything acidic!!
