I might suggest Stan, to augment the play-dough trick, a sheet of waxed paper as the first layer, then the play-dough, then the compression to fit, would make the removal of the imprinted play-dough easier later. I use play-dough to mask off wood when using Acura-Glas, and this trick sometimes saves time of the removal of the detritus later. RWTF
