I am trying to find some kind of body filler or putty that I can use to fill quiet a bit of space. I need something that I can apply about 1/2 inch thick. I have tried regular bondo, but I haven’t been about to get it thick enough because it is just to thin and hard to work with. So does anyone have any suggestions? I also thought that there could be something that I could mix in with the bondo to thicken it. But I don’t know what I could use. So if anybody knows something that would work to thicken it I would try that also.
