Paintless Dent Repair vs Traditional Bodywork

What paintless dent repair actually is

Paintless dent repair, usually shortened to PDR, moves the metal back into shape without touching the paint. The technician works from behind the panel with long rods, or pulls from the front with tabs glued to the surface, and massages the dent out a little at a time while reading the reflection under a light.

Nothing gets sanded, filled or sprayed. When it works, the panel keeps its original factory paint, which is the best finish that car will ever have.

That last part is why people ask for it. The problem is that it only works on a specific kind of damage.

When PDR is the right answer

A dent is a good candidate when all of these are true:

• The paint is not cracked or chipped. PDR does not repair paint. If the paint is damaged, the panel needs refinishing no matter how the metal is fixed.
• The metal is not creased. A soft, rounded dent can be massaged out. A sharp fold has stretched the metal, and stretched metal does not go back to where it was.
• It is away from edges and body lines. Styling lines and panel edges are stiff and hard to reach. Dents there rarely come out clean.
• There is access. The tools have to get behind the dent or grip it from the front.

The textbook case is a door ding from a parking lot: small, shallow, in the flat middle of a door, paint untouched.

When it has to be traditional bodywork

Everything outside that list. A dent with cracked paint, a crease, a dent that crosses a body line, one on the edge of a panel, or one where the metal has been pushed well past its shape.

Traditional repair means the panel gets worked back to shape, any low spots are brought up with a thin skim of filler, and then it is primed, blocked straight, painted and blended into the panels next to it so there is no edge for your eye to catch. Done properly, the repair is invisible. Done cheaply, it shows as a wavy reflection or a colour that does not quite match.

Aluminium panels deserve a mention. They are less forgiving than steel under PDR, so a dent that would pop out of a steel door can be a bodywork job on an aluminium one.

The honest trade-off

PDR is usually quicker and cheaper, and it keeps the original paint. Traditional bodywork takes longer because of the paint stages, and it costs more because it includes them.

What you should not do is push for PDR on a dent that is not a candidate. Forcing it tends to leave a panel that is almost straight, with a ripple that shows in every reflection, and then it needs bodywork anyway. The same logic is behind why we usually put on a new bumper cover instead of patching a damaged one: the cheaper-looking option is not always the cheaper one.

How to read your own dent

• Look at the paint up close. Any crack, chip or flaking means paint work.
• Look at the reflection. A soft dip is a better sign than a sharp line through it.
• Check where it sits. Middle of the panel is good news. On a body line or right at an edge usually is not.
• Send a photo. One straight on and one at an angle tells us most of what we need.
