Filler Question

What brand/kind of filler do you guys use to do your "final" smoothing of a panel? I have my doors and shell close enough to flat for me to be thinking about how I will proceed to finishing it off. I have been using Evercoat lightweight filler so far and it seems to really harden quickly. Maybe unreasonably, but I am looking for something that takes longer to kick so I have a little more time to smooth on a skim coat. I am mixing it with only the same brand hardener, should I be doing something differently? I have played around a little with the ratio, but it doesn't seem to affect the hardening time too much. Thanks for your help in advance! L8r

Don’t mix the Hardner with the filler until the last minute. Apply the hardner to the spreader paddle, take the board with the filler and the spreader with the hardner over to the panel that your working on and mix it right there. This gives you an extra minute or so, sometime that’s all you need. I do bodywork in south Florida and this stuff goes off in a flash. I agree with the others, mix small amounts unless covering an entire panel
