how does paintless dent removal work?

Answer 1

contrary to popular belief it is not suction cups

Mostly they use large metal rods to reach in-behind areas of dents and gently push them out. It is very tedious and can be very frustraiting it is really a skill. On areas that do not have access to get behind (such as double folded metal) they will used what is called glue tabs. they put a dab of hot glue on the tab and place it on the center of the dent. When the glue dries they use a plung hammer to pull the dent out. This is the least favorable method because it usually doesn't come out on first try, and it can also put high spots in the metal that must be gently worked back down.

Answer 2

There are different techniques, but basically provide the same result. If you have a dent without creased edges, they can often be removed by gluing a tool to the dent and pulling it out, pushing out the dent from the back, or by heating and cooling until the dent pops.

This is a new repair technique that is being pushed hard by the insurance industry because it is much cheaper than fixing the dent and refinishing the vehicle.

One big caution is that when the dent is made or repaired, the paint can become detached from the metal. It may not come off and you might not notice it right away, but over a few months, moisture can collect under that paint on top of the metal. The result will be rust spots. You may have seen some of these vehicles going down the road with rust spots on the hood, trunk, or roof. That was likely the result of paintless dent repair.

Answer 3

You basically glue a screw device to the dent.

Answer 4
