question for Peter J. Blackburn



Some weeks ago someone posted a link to Peter's very interesting gum article. In it he said that he had found specific paints by specific makers which did not stain. Apparently, Peter is not on the list, but I hope someone who knows him will ask if he would identify two or three of his successful triads.
