  1. WARNING : just to let Amateurs know… you should always wear a proper respirator + Goggles when sanding or painting etc… unless you like chronic chest problems or missing eye syndrome , i would also recommend overalls , ventilated area , gloves , steel toe boots , patience

  14. Thank you so much for this video sir. I'm a rookie body tech assistant and my lead hasn't really taught me much about the techniques of body filler spreading and sanding. This helped a lot. Cheers and thumbs up!

  15. I laugh you can't use bondo for auto body for the other things we don't do on bondo that why people get wrong ideas about destroy bondo they don't reading in correct books need change otherwise red chrome hardener for other things …………………

    another tip… I found that the filler, even when cured. will be tacky on the surface, and ca clog your sand paper. A trick I came across, is to wipe it down with thinner before sanding. Saves on wasted sand paper

    was looking good until you used the same spreader you mixed with to apply the filler. i never do this. i've been using 2 sometimes 3 spreaders when applying mud for over 25 years. why 3? one mixes it and gets set aside. the 2nd spreader i use to force the mud into the ground and sanded metal and gets set aside because ground metal will ruin the edge of a plastic spreader. 3rd spreader will apply the build coats.. and i always make sure i start with smooth edges on my spreaders by "sharpening " them with cardboard…try it, get the feel for it and you will never use sandpaper to smooth the edge on your spreader again. clean your spreaders as quickly as possible , with thinner. don't soak them in thinner or leave them in bondo as both will prematurely distort the spreader. i throw away more spreaders in a month than most people will use in a year. i'm anal about spreaders, i'm anal about mixing and i'm anal about applying filler. i go for perfection whether its a honda or a lexus or a harley or a pedal car.
