I believe that I read somewhere that there is a product that can be added to the final layer of a Vinyl Ester Resin lay-up, that will make it easy to sand. Does anyone know what it is and where I can get it?
Daniel R. Heath ++++++++++++++++++++++++++++++++++++++++++ Dan, On a single curve surface you can wet out a sheet of peal-ply (Dacron) over the last layup available from Aircraft Spruce. After the layup is cured, peal off the peal-ply to reveal a mat finish surface ready for painting with very little sanding. For compound curves where the peal-ply won't conform, make up some micro with the Vinyl Ester Resin and micro balloons (glass beads) fairly thick, but still wet. Slather that on and let cure. The micro will sand very nicely. The Vinyl Ester tends to gum up on the sand paper, especially if you power sand. Hand sanding works well with the micro. To prevent the gum up, keep the surface wet with water when you sand. I used an old windex spray bottle with plain tap water. Wipe the residue off the sand paper and sanding surface often using a paper towel. A sheet of wet sandpaper will sand an entire wing with micro.
