Touch up Spray Can Color# 1C8?

You can try going to a local body shop and asking them to mix up a pint or so and then get yourself a hobbyist's airbrush kit.

hmm, I know I can get mixed paint at Napa. But what airbrush kit you are talking about? I don't have air compressor and paint gun. Can airbrush kit get me same quality? I try to avoid cheap one that push out big dot of paint (for the wall is OK).

For touchup purposes, a good airbrush kit works better than an aerosol can.

An airbrush kit is basically a mini paint gun. They can be connected to a regular air compressor with an air pressure regulator, to a mini-compressor, or to an aerosol can filled with plain air. Look at a hobby shop or woodworker's shop for this setup.

The airbrush kit hooked to an aerosol can with plain air is probably the least expensive alternative for you if an aerosol paint can is not available.
