Alternatively some waxes might do well; they are already used in several different commercial RP machines.Adrian Bowyerhttp://www.blogger.com/profile/17595509188999219420noreply@blogger.comtag:blogger.com,1999:blog-12223283.post-1114375832847777382005-04-24T21:50:32.846+01:002005-04-24T21:50:32.846+01:00"...opened the machine, and painted a thin film of vegetable oil (Tesco's own-brand Corn Oil, to be precise) on the top surface..."<BR/><BR/>How about using something less fluid that could be fed through a syringe but would stay in place while the part is being constructed?
