This is mine , Just make sure you have no raised alloy , before applying alloy filler, is really good and silver , Then sand flat , I used no primer as this effects the finished colour.
Just make sure the repair is good before painting ,if you can feel it with your fingertips with your eyes closed, it will not be good enough.
Two or three coats of colour semi drying between coats ,say 5 mins ,then two coats of lacquer with delay between coats to flash off .!
I now have to really study the wheels to find repair!!
