I was wondering if I could just fill or just coat the the > circuit board and its components with epoxy? I wouldn't. It would make the board completely non-servicable in the future.

If you want to pot it, use something that does not attack the parts and that remains flexible when cured. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ------------------------------------------------------------------- List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
