Im teaching myself to do bodywork right now, so far ive straightened a badly crushed piece of the car pretty good. Now Im using bondo to smooth it all out. While i was at it i figured that id shave the door moldings too. Does anyone have any tips for this? Do I just fill the gap with bondo or what? Ive seen it done before, how do people normally do this? Do I drill holes to make the bondo stick in there better? Will It crack or mess up after its been sittin on there for a while? I just want to do it so it looks very good and last forever. Somone please give me some pointers or links to a site that shows how to do this.
