The more elaborate these paints/colours become, the harder they become at matching....adding flake to the equation complicates the match...the pigment might be spot on, but the flake may be bigger/smaller heavier/lighter, so it tends to settling lower/higher within the coat sprayed...
38 samples were made with varying formulations to match my Candy Red paint tri coat...these were 6" x 6" automotive mild steel cutouts body shops generally use to colour match.....One of BSAF colour specialists showed up and worked with the master painter before they hit the magical point...
The FORD body shop I used has up to date tooling....Mike ( the painter) ended up using a specialized spray gun for flaked ti coat that has a small slow rotating prop inside the paint holder...this keeps the flake suspended and moving as he applies paint....was very pain staking process to get that right....
This was a slight rear end hit that marred the bumpers paint, so the outer skin (plastic bumper cover) was replaced, primed, sanded primed and sanded again,then sealed with a flex agent.....flex agent was also added to the final coats (3) to keep it playable over it's life,then 2 coats of clear coat PHEW!
My paint is one of the nicest and deepest I have seen on any car....something about a proper candy apple red that is full of depth and dimension....it actually looks like it's a 1/4" thick!!
Only hand washing and best of the best waxes go on that paint,and trust me on this....my wife always has some comment about me "NOT pampering her as much as I do my "Stang" LOL...MEN!!!
The driver that hit me, a neighbour, started freaking out she hit my car while it was PARKED in my driveway...she was cool enough to say, fix it and give me the bill...that was almost $2,300 after taxes, and a week at the body shop!:eek
