After trying to source replacement grills for my "Atlantic" and realising that the top "square headlight grill" is as rare as rocking horse poo! I've decided to spray them with a satin finish paint. Now for my questions:
1) should I sand off what remains of the chrome.
2) What type of paint can I use and does it come in spray can form.
3) Do I need to use a spray ???? as a "key" to allow paint to stick.
Any tips, advice or mild abuse would be welcome
