Thanks for posting that informative article, Artie. Rubbing alcohol is available both as isopropyl alcohol and ethanol that has been denatured. I prefer IPA as a rubbing alcohol because goes on more smoothly. In any event, I will probably use IPA in MacManiac's method because of the caveat about denatured alcohol causing damage to plastics and its propensity to leave residue.
