I will need partial repaint of my xB ( driver's side) and want to know what brand name of paint to use to get the closest match to the original TCM paint. Thanks in advance.

 

Brand is not relevant really. A good color match technician is the key. He can tinker the formula to match the actual car. All cars vary a bit within a given color code. You ARE talking about professional products I hope...like mixed and sprayed with a spray gun?? I would not trust any formulated color match prepackaged or mixed for a precise match. TCM can be varied quite a bit by spray technique actually as well. Heavier coats will result in a bit darker face and light coats a bit lighter face. Find a match man and get major brand basecoat (PPG, Dupont, Sikkens, BASF, Valspar, or whatever).
