Micro Spheres
Andrew,
Stephen is correct. Micro Balloons or Micro Spheres are the way to go. I guess I should know we make Polyester / Vinyl ester and Gelcoats resins here at my work (Huntsman). Most good quality outlets sell Micro Spheres in various sized packets. We do have outlets in Vic and Qld but good outlets will stock these products. Look up Huntsman Composites in the phone book / web they can tell you where you can get it.
Micro Spheres are a much lighter product and designed for large fill jobs that need sanding. The glass beads crush as they are sanded and there is less weight due to the air in the sphere, this is why they are easy to sand. Talc is OK for the finer details but is heavier. You just need to use a good quality bog (Bog has fillers and talc in it already). We supply K+H product with our resins.
A good point already mentioned about wearing good breathing protection. WEAR IT!!. We dont want any dead cobra owners on the forum.
Cheers
Tony
