This is how Paintless Dentless Dent Repair Really Works
1. '''Direct leverage'''. Gaining access to the metal with direct force on the dent, from behind. This can be done behind your factory bracing, through sound dampening pad, and on body lines. This method traditionally requires removal and reinstallation of parts or the creation of access
and it works on metal, aluminum, and HHS.
2. '''Indirect leverage'''. Gaining access within the recess of a panel and using a bridge to affect the surface by creating a fulcrum.
3. '''Glue pulling'''. The process of pulling the surface of the damage with specially formulated hotmelt glue in conjunction with hardened plastic or metal tabs. Once the glue and tab are attached to the surface of the painted surface, it is either lifted with a slide-hammer or a mini-lifter. Typically, a slide hammer shocks the metal with a very strict upward jab, while a mini-lifter provides a more direct and slower progress upwards. The results will vary based upon the size of the tab, the type of glue that is used, and they type of puller used.
4 '''Tap downs'''. There are a variety of tap downs, but the most common are sharp to medium acrylic, which leaves light traces once the panel has been struck, but can easily be polished out. Medium aluminum which is used for more specific work. Sharp steel, which is used to slightly crush clear less that .5 of an MU which can be wet sanded out.
