Anybody have an opinion on how to refurbish a 330 grill without taking it apart?
They are quite easy to take apart - and then you can really do a good job polishing the aluminum. Take good photos first so you can put it back together correctly. John
Simichrome polish with cotton towels / tee shirts works well. It is labor intensive - as I did small area at a time under good lighting.
If you put 'grill' into the search area here you will see someone else (Tom Yang) doing what you are asking about: http://www.tomyang.net/cars/ferrari.html
