Cleaning the spreader is simply a matter of a couple of things depending on weather it's "bondo" or glaze.
Bondo likes to stick to whatever and I wipe off as much as possiable and then clean it with lacquer thinner and a rag.
Glaze,I let what's left harden up and then bow the spreader a little and the majority will pop up and you can pull it off,then I finish cleaning as above.
I have a tub of old thinner and toss it in for a few minuits and then wipe it off.
repete as needed. Worse case,is to take a clean metal putty knife and scrape on a flat surface without gouging the plastic spreader and then lacquer clean it. Metal spreaders are best wiped down and dunked into the thinner and then wiped off cause you can't bend them much.LOL..
I'm sure you all appreciate Brians vid but this "trick" was provided by badbob over at hotrodders years back and that should be recognized as well.
