Yes, wear gloves. I got that stuff in a small cut on my finger once, ouch. :-( I have tried hair blow driers, but that doesnt seem to work too well.

It also helps with spills. - Ben -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
