Hi PD's - this is nearly

...but here goes
A twenty metre roll of 50 mm wide of what appears to be conventional translucent FLY SCREEN material... from your local hardware shop
Is the same size & mesh opening ....but it is a mono filament fiber glass 0.005" diameter
PLUS it is self adhesive on one side only ...and @ $AUD4.00 per roll is pretty good value
This could be layered up X 3 or 4 thicknesses [out of phase or mesh] & would save countless tubes of SupA - GLU :ohno & glued up :rant fingers + :sob prior to the pouring of the liquid epoxy resin + hardner........ Derek
