Tom,

Do you (or any other Teches out there) have some names of companies that I
can get in touch with that deal with Turpene.  I'm pretty new at this so any
help would be appreciated.  Do you also know how well  it cleans flux and
how compatible is it with elastomers/plastics?

Thanks,

Kathie Lucas
