HELP, I picked up a gallon of body filler two days ago. I mixed a 1/2 cup or so with about 3/4 inch of an old tube of hardener. Applied it and it didn't set very well ... about an hour later in a warm shop all it did was ball up and fill the paper right off - no dust. I mixed up some more about the same quantities with the new hardener and darn same thing ... I have a heat lamp on it right now but it's still kinda soft 12 hours later ... what do I do now?
