How to Use Body Filler to Create a Good Finish

So these days, there are lots and lots of different types of filler. Filler used to be a bottle of resin, a bag of talc, and then some catalyst as well. And you mixed it up like porridge, it set like concrete, and you'd have to file it before it set fully to start getting a shape in and everything. Well, those days have gone. Modern technologies come up with a new recipe for it, includes something called silicates. They're like hollow spheres almost like ping pong balls, if you will, that are inside the filler and they make it easy to sand. They lighten it as well. Cause if you think a piece of talc is a solid piece, whereas these have air inside, so it's easier to sand and light away. So there's a whole, whole raft of different ones that you can go for. The two that we're mainly going to look at today are this one, which is a fiberglass filler. That you can go over the top of, not completely welded joint. So there's a gap in the joint. Or if you must, go over some holes. Cause what that is, that won't take on any water. The normal body filler that we would use because of the talcum powder in it, it is talc, so it will absorb water. If the water's next to your bare metal, it'll start rotting and rust, and then you'll get adhesion problems with your filler. So this is the filler we're going to use. It's just normal, lightweight body filler, for use on all the different dents and bumps on your car.
