You can buy pre mixed auto paint from a parts store, the run about $24 a quart.. Or even NAPA has pre mixed basic colors for cheap, and some NAPAs can mix any color or type auto paint you want at a fair price.. But if you go to an auto paint supply shop, heres a lil secret... Any and all factory colors are exact matches, which require a paint code they have to mix by so they come with a steep price.. Blacks, whites and basic colors are cheapest.. Blues and greens are mid priced.. and reds and pearls jump pretty steep.. BUT!! If you DONT use a factory color, and need them to make a color.. Its WAY cheaper! Usually they will give you a 1/2 quart to try and see if you like it, and will keep tinkering with it till you are happy with the color
My wifes car needed the spoiler painted, we played with white pearls till we thought it matched close enough to the factory color... Cost.. $4 for the quart.
And my lawn mower is close to Dagen1s truck color..lol, $6 for that quart.. Got bored and was wondering what a green with gold pearl in it would look like
And another helpful tip with fillers and stuff at an auto paint supply shop.. they have scratch and dent cans
and usually if something got spilt on a box of something they will discount whatever was in the box.. I got Evercoat kitty hair, gallon, usually $70ish.. for $10. The plastic 3M epoxy for bumper repair, usually $45.. for $14.
