Base coat problems?????

[Chevyholic]

I am in the process of finally spraying color on my project. I am looking for a darker metallic brown. I bought metallic chestnut brown from paintforcars.com because the picture portrays the exact color I want. I sprayed one of the doors and the color came out lighter and with a bronzey/brassy color. I looks nothing like what I thought. Can I have a local paint shop add to the paint to darken it up? I have also read that a darker (black) primer/sealer will make the base coat darker, is this true? I used a basic grey sealer, if I use black will it turn out darker?

i just painted my truck a month ago. a 2 tone, charcoal and gunpowder. well, the gunpowder color came out looking silver, like a coors light can. the next day, i went back to the paint shop and had them keep adding black until it darkend up to my liking.
so, yes, you can take it to a paint shop and they will darken it for you.
yes, the darker the primer or sealer that you paint over, the darker your color will be.
also, play with your air pressure. spray an area at about 20 psi..............then spray an area about 30-35 psi or even 40 psi. see what pressure you like the most. it will come out lighter, darker, more, less metallic.

The only way a local store can add to your paint is if they carry the same paint line that you bought online. Your undercoat coat color does affect your basecoat color to an extent, if you're not spraying to complete coverage. Otherwise, it doesn't matter, with enough coats any color will "hide" the undercoat. If you're shooting two coats do three. Four is the max I would go on basecoat though. Also, if it's coming out bronzey, there is a chance your metallics and micas are settling to the bottom, and not staying suspended, while you're spraying. (certain colors do that, just depends on how heavy the metallics and micas used are). Try to spray a couple test panels, one over grey one over black, one coat at a time, aggetating your gun between coats to keep the color suspended, and see if that helps and you get the color you want, othewise, you might try to contact paint for cars and ask them what you could get to make the color darker.
