After many years of playing with ordinary epoxy and Elmers woodfill, I
have graduated to Bondo

Any tips with how best to measure, mix, and handle the material.
The can I bought comes with a measuring cup and talks about using a
1.5" bead per cup.

- Do you mix it all together in the provided cup or do you use
something more disposable?

- How precise do you need to be in measuring out ratios of materials?

- Any tricks for applying and shaping the mixed material? (it seems to be very
sticky)

- Any way to get a longer work time then 3-5 minutes?

Thanks for the advice
