Lessons in bond

I'm filling the imperfections on the robot with bondo. Wow, if you put too much hardner in, it's hard as a rock in about 30 seconds !!! I won't say how I know. I think I put too much bondo on the robot in a few places which means lots of unnecessary sanding. I thought I learned that lesson many years ago while trying to do some body work on a car. I probably shouldn't have used bondo and just used that soft red filler because the spots that need filling aren't very deep
