I googled "bondo tips techniques" - first hit: http://tinyurl.com/7rfky


Interesting articl and thanks for the link, but:
- It doesn't really answer any of my specific questions
- It is targeted to body shop repair while I am interested in it more
for *home* repair uses such as filling wood defects, etc.


http://tinyurl.com/d3c37 That's the search for "bondo tips techniques
wood repairing". There's plenty of stuff in there about mixing and
techniques.

The stuff isn't rocket science and you'll find your own preferred
methods of work. I've heard everything from mixing it in a plastic bag
to doing it on a piece of glass. The proportions aren't super
critical. The hardener is a catalyst that causes the filler to harden.
You can vary the properties of the final product by varying the ratio
of the two components in your mixture. A greater proportion of
hardener will make the bondo cure more quickly and be less flexible.
Not enough hardener and it will never harden correctly.

Usually when you're mixing a two-part material with catalyst it's an
exothermic reaction and the heat can be a problem as it speeds up the
reaction. Some people refrigerate the components prior to mixing, but
that makes it tougher to mix and won't buy you a lot of time. In that
situation you should look for another product. Bondo has a lot of
different products and several different hardners. You're not limited
the the stuff you find at your local hardware store, nor to a
particular manufacturer.
