Actually to the contrary, automotivetouchup.com makes great dealer replica paints.
Make sure to get it in the arousal can.
I used this on a specific Red Perl on an Acura, and it was dead on a match. Now of course new paint does not perfectly match old paint becuase well, its old. The paint has faded a tiny bit, and the clear coat will look different.
So it will be like 2% different looking than the rest of the car.
Will it be noticable from 10 feet, probably not.
If your cheap and just want to get it done for under hundreds of dollars, this will work, but it will not look 100%.
Post pics when your done.
