I am Chris Gilliand, the owner of DentsUnDone, working in this profession since more than 20 years.
Multiple locations in Huntsville, Alabama, Madison County and surrounding counties Monday through Friday.
The most common methods of paintless dent repair utilize metal rods and body picks to push the dents out from the under side of the body panel. Additionally, glue and a specially designed tab may be used from the outside of the panel to pull the dents out. In either case, fine-tuning of the repair often involves “tapping” down the repair to remove small high spots, or shrink the metal, making the surface flat. Paintless Dent Repair may be used on both aluminum and steel panels. Quality technicians blend high spots to match the texture of the paint. (note: If a technician pushes too hard they will create severe high spots and the clear coat may split or crack.)
Experienced technicians will not crack or chip the paint 99% of the time, although if the painted surface is not in good condition or the metal is too cold it can crack and even the very best tech can not stop this from happening.
When damage is too great and body filler is necessary a body shop may request a technician to do something called “push to paint”, which involves pushing a majority of the metal up because the body shop is going to repaint those panels anyway, this saves time and money.
