Here is a correction. Talc is the primary ingredient in most body fillers for fairing purposes. The West System 405 is cellulose powder (sawdust-very fine), pecan shell powder (very hard cellulose type material) and silica (sand). That is from the MSDS data sheet. It is also interesting that a very good adhesive for veneer (and possibly belly work, as well), is Better Bond which does not creep as most other PVA adhesives. For that matter most all adhesives other than hide glue have potential for creep. It's secret ingredient is ground pecan shells. Pecan shells must work more or less as sharp aggregate ( limestone) in concrete to stabilize and strengthen the product. It is only slightly more expensive than titebond and worth using routinely where a PVA adhesive is needed and creep can be an issue. . My routine favorite PVA adhesive is Weldbond that beats titebond for strength and has some flexibility. I use it for almost everything except veneer work. Not for veneer work because of possible creep over time. It can be softened with acetone, making it reversible. Reversibility is a very important feature for anything that you ever want to take apart in the future. That is also true of hide glue and is probably the main reason hide glue is still around.
