9. * Conversion coatings are very nice "paints" that allow other paints to stick to aluminum. Type 1 coatings are thicker than Type 3, which are whisper thin. Alodine 120X (Amchem) and Iridite 14-2 (Allied Research Products) are good conversion coa

You weren�t clear but I assume the problem is not widely distributed and affects only a few parts on each board. Do this trick: * Cut a ~1� piece of fairly serious wire, like 18 or 12 AWG. * Strip the insulation. * Gear-up with gloves, glasses, and
