I've revisited playing around with Marie O'Connell's wet play technique but have come to a dead end as I need as a test sample an actual squealing tape which does not respond to normal baking. Marie mentioned PEM 469 of which I have many reels but the samples I've tried seem to play fine. I also have much 3M 177 but reports on that seem mixed. Perhaps that's related to the moderate Mediterranean climate here in Perth, Australia. Richard Hess mentions 3M 175 and some others but what would be the most common known bad cases? I may have some here in my collection but it would shorten the process if I could narrow my search down to certain tape types known to squeal regardless of baking. Thanks for any advice, Tim Perth, Western Australia ------------------------- Email sent using Optus Webmail
