hey guys, looking to touch up my tail light surround and front corner finisher of my 72 ke20. but just need a lil help on a few things. firstly , in detail, how should i prep them e.i sanding, this is also including my front grill , lip and bonnet lip. which in this early model appear to have all been painted with a flat sorta silver. secondly what is the colour, original, of the silver i need. is it matt, gloss, shiny dull etc.
cheers
