Have been playing for the first time with with BONDO to fill in some siding

Boy, the stuff sure sets-up quickly; a matter of a few minutes.

Is there any way to lengthen the set-up time, without degrading any of
its other properties ?

Sure -- mix in the correct amount of hardener. If it sets in a few minutes,
you're using too much.

Set time also varies with temperature -- the hotter it is, the faster it sets.
If you're storing the stuff in your garage, try storing it inside the house.
Then take it out to the garage to mix it, and bring it back inside when you're
done.

Main problem, though, is that you're mixing in too much hardener. The easiest
way to avoid that is to buy a few of the plastic spreaders that they make for
it (you should be able to find them at the same place you bought the Bondo).
Mix in just enough hardener -- and NO MORE -- to make the mixture the same
color as the spreader. That's why they make them that color.
