Mixing board and spreaders

I purchased a plastic mixing board for a couple of bucks which resembles an artist's paint mixing board. It is well worth the money as it is very easy to hold and to work with. It is also easy to keep clean which in body work is next to godliness. After every time I mixed and spread the filler, I cleaned all my tools before I mixed some more filler. Otherwise, you'll get lumps in the filler which cause great havoc while spreading. I had a dedicated metal paint scraper that I used for scooping out filler from the can and which I mixed with.

Quite a few bodymen, take the extra time to clean their mixing boards with acetone after each use. They claim that even trace amounts of old filler can contaminate the new mix. Some say it causes the filler to take longer to cure or not harden at all. I would think that the opposite would be true but who knows. I'll give it a try - anything to improve! BTW, it's pronounced "ah - sah - tone" not "ace-tone" (from my chemistry days).

My spreaders were used only for spreading filler. You can buy spreaders that are color coded for the correct color of properly mixed filler/hardner. This is handy when you are first starting out. The instructions are pretty vague on how much hardner should be added. I try to use the widest spreaders that I can so that I minimize any waves in the filler. I alternate in the pattern that I spread the filler too. I only put on a maximum of 1/8" at a time and give it plenty of time to cure. It says that you can start sanding after 15 minutes but my garage is on the cool side and I give it a complete day to be safe. Otherwise you clog up your sandpaper pretty quick.
