Thanks Keith, Is the polyester resin coating something of a 'do-it-yourself' project? There is four 1" openings on each tank, so I should be able to pour the resin (or spray) and rotate each tank for full coverage.
However, I inquired further with a resin company on the internet and waiting to see what advice they have for me. -Kevin ----- Original Message ----- From: "Keith Addison" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Monday, November 01, 2004 8:52 AM Subject: Re: [Biofuel] Fw: Biodiesel output to galvanized settling tankw/site tube > Hello Kevin > > >Currently I process BD as single-stage, but hope to grow into the acid > > two-stage down-the-line.
