Video Transcript

"Hi, I'm Doug I work with 20 great guys in Saint Louis at Doug Jenkins Custom Hot Rods and we are going to do some work for you today on Expert Village. Now Alex is going to be mixing the traditional body filler. There are several different brands of this 3 different brands that we use and like most things you get what you pay for. So we buy the most expensive kind of body filler. When you are mixing body filler you want to be careful to fold it over and mix it thorough but you don't want to mix it to aggressively. If you mix it too much and do it at the wrong angle, if you fold it too much, you would get area bubbles in it and when you go to spread it, those air bubbles may or may not show. But when you sand it you would end up with little pin holes that you have to fill later. So mix it carefully, mix it slowly, and mix it with the right amount of filler and follow the directions. When you mix the filler and the hardener use the right amount of hardener the directions say about 1 inch of hardener for every golf ball size bit of body filler. That is a good frame of reference. If you put to much hardener in there it actually slows down the filler from setting up when it is on the car. If you to little it slows it down as well. "
