What makes a brand better than other and is one better on certain cars for matching the paint?

I ask because a couple years ago I had an accident and when the work was completed, the cars paint was off. I had them repaint the car a second time and it was very close but if you stared at it it was slightly off. I didn't want to have the car down for another week so I decided not to have them redue it again. I figured if you can't match it on the first or second.
That shop used PPG paint.

Just got into another fender bender and am deciding on another shop that uses DUPONT.
I could go back to the other shop but they left a sour experience for me.

It's so hard to find a good shop you can count on not to mess up your ride.

BTW the color they were trying to match was Tungsten Pearl (silver)

 

i think akzo nobel has a really good paint matching system. their swatches have toner's that show whether a color is clean/dirty... and which direction on the color wheel that its closer to... makes life a bit easier when matchin paint....

silvers are among some of the hardest colors to match. along with those, golds.

 

ppg is a very good product. most ppg shops will also use the lesser of the paints, ppg has brands they make of less quality but still ppg.
one thing to know is that you can have the exact same color in the gun as what is on the car, and due to temp, humidity, distance, gun pressure, etc. etc. the color can be different everytime it is sprayed. so many variables that it is retarted...
i like ppg, never had an issue. omni i think is ppg'd cheap brand., color match sucks with them.

 

I think the best way to do this is to match the color of the paint with the one that will be mixed. Take something like the mirror or a fender to colormatch, and let the mixer tint it till you get what you are looking for.

 

I also heard silver was a hard color to match. I guess it doesn't make it any easier also if it's a pearl too.

I leaning towards going to another shop still. Hopefully I wont regret that choice.

thanks for the info guys

 

silver is supposed to be one of the harder to match. it also depends on the condition of the paint on the vehicle. its really hard to get paint a 100% match, even if you have an experienced mixer or a machine to do it for you. most painters earn there money in blending ability. they try to make the change in color so slow that it is almost completely unnoticable.
