Lots of great info. For single stage solid colors some manufacturers have an option of adding clear to the final coats after coverage is achieved. This is not over the single stage but into the single stage. Concerning tinting and White in particular. White can be hard to match since most starting formulas already contain black and/or chromatic colorants (red, yellow, blue, green, etc.). Therefore when adding additional colorants to an existing formula, the hue of your white can move a completely different direction than the colorant added; its called "crossing the color wheel" which cannot be corrected by additional colorants; the only fix is starting over with a new mix. Example: if the white formula includes yellow and then you add blue (to make the white "bluer") the white becomes "greener" not "bluer" (blue and yellow make green). The best option in this example is to leave the yellow out of the formula and add blue if needed. Hope this brief "color theory" is helpful.
