If anybody wants to try this, make sure you get industrial talc, and not the bottle of Johnson & Johnson from the bathroom cupboard. While it does have the same base the stuff you get from the supermarket has additives that react differently when mixed with paint/resin. I've seen people try to make filler and glue with epoxy and this stuff - it doesn't work (it slumps and is weak).

Also, if you want the best results with talc, make sure it is dry - its better to buy small packets and use them up within an hour or two of opening. Otherwise, you'll have to dry it before using it.

I wouldn't recommend using talc for anything, if you want to find a filler or a texture additive for paint/resin all of the big poly and epoxy resin systems have additives available and they are generally much better - because they are not flammable they are easier to order online/by phone than the resin itself and you can usually get them posted to you.
