Bob gives us an idea of what is involved with Harley fender dent removal. In many instances replacing a fender or fuel tank is much less expensive than having a professional labor over correcting the piece. In other instances the damaged component may be rare or one of a kind and repair is the only option.
Before attempting any type of fender dent removal or bodywork it is of utmost importance that you purchase or borrow not only the correct body tools but also the necessary safety supplies for the work you are to attempt. Body work involves dust, vapors, chemicals and noise. Always use masks, respirators, safety goggles, gloves, & ear protection.
A dent is a recess in the metal. When the recess is created, metal transitions to another area in the structure. That area will now be distorted, raised, or rolled. This is the hard part of the damage. The area opposite is considered the soft part of the damage.
Determine which side of the dent has the least amount of damage (soft) and that should be your starting point. Always work a little at a time. The repaired area must be lower than the final surface of the component. This allows for filler and/or putty to be used. A metal file should always be used to knock down high areas. Be sure to use the file over all contours and in every direction to create a cross hatch pattern when performing fender dent removal.
Taking extra time and care in this step of the process will have you filling and sanding less later.
