KR> Slick finish.
Hi Mike Over here we have been using the dry micro method over the layup for the construction of all Whisper motorglider wings, stabilizers and rudders. The surface is covered in a light "sacrificial layer of glass to cover any gaps in the weave of the heavier biaxial structural layer underneath. we then pour on a generous amount of dry micro and lightly massage it into the weave of the top layer. This goes a long way to eliminating pinholes and after sanding the wing down with a "longboard" untill roughly halfway through the sacrificial layer an 8m long wing can be faired to final coat stage with less than 1kg of resin/micro mix.

Who knows...you might reinvent another wheel for us... Mark Langford N56ML "at" hiwaay.net website at http://www.N56ML.com
