I hope it was useful; it took quite a bit of experimenting to get a reliable and reproducible method, so hopefully will be beneficial to somebody in written form. Meths was used as an abbreviation for methylated spirits, aka denatured alcohol I believe. It's usually pink, blue or purple over here due to the additives. Must be a British abbreviation :) Regards, Pete Restall -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
