Hi Stan and BTB ..... I plan to experiment a little by writing, leaving for a couple of days to really set, then apply a thick layer of tippex and leave for a week or so before attempting to remove it. As the inscription is important to me, I shall find the patience to do so. Am I correct in assuming you mean the old fashioned gillette style razorblades? If so, shall also buy a rubber eraser to stick the other end into for protection. If that makes sense! Antonia |
