"ben is there 3 diffrent shades of the ice berg silver or just the 1??"
I have just spoken to my spray shop about this topic.
Iceburg Silver has 2 shades on most bodyshop matching cards. BRIGHT and NOT SO BRIGHT.
I got Iceburg 640 from Halfords, it was a reasonable match straight from the tin, but Renaults are painted very thinly indeed. The bodyshop save a fortune buying paint for Reanults ( they charge you for normal use but they only need to use a tiny wee drop to match factory paint )
Plus, you really need water based paint made up ( warranty and EU laws etc ) .
One way I found to get it matched, was to use a hobby spray gun, where you can use thinners ( about 3 - 1 ).
The clear coat is a totally different ball game though. Some professionals will actually mix the lacquer into the paint for a "factory finish". This cant really be done using Halfords paint cans.
Tip 1. Do not put any polish on the newly painted panel for at least a week. ( the polish eats into the paint, softens it and then it simply peels off. ( at high speeds )
Tip 2. Get it done properly by trained sprayers who will bake the paint in an oven.
PS. This is only my bodyshop mans opinion.
