Paintless dent repair: what it fixes and what it can't
PDR turns a big panel bill into a few hours' work, but only on the right kind of dent. What actually qualifies, what a job costs, and where it stops working.

What PDR actually is
Paintless dent repair is a set of specialist tools and access techniques, not a chemical or a gadget. A technician works from behind or beside the panel with metal rods and picks, or pulls from the front with glue tabs, gradually massaging the metal back to its original shape without breaking the paint's surface. Because the factory paint and clearcoat are never cut or sanded through, there is no colour-match risk and no filler, which is why a good PDR job is invisible and holds its value on resale in a way a respray never quite does.
The dents PDR actually fixes
The technique needs metal that has stretched, not torn, and paint that is still intact over the dent. That means hail damage, door dings, shopping-trolley knocks and shallow creases from a low-speed knock are the classic candidates. Access matters as much as size: a dent in the middle of a bonnet or roof with clear space to work behind it is often an easier, cheaper job than a smaller dent hard against a door edge or wheel arch where a technician cannot get a tool in.
Where it stops working
Cracked or chipped paint over the dent rules PDR out immediately, because the process relies on the paint film stretching with the metal rather than flaking off it. Sharp creases where the metal has folded rather than stretched, dents over a bodyline or crease pressed into the panel at the factory, and anything on high-tension areas like the edge of a wheel arch are all much harder or impossible to pull back cleanly. Deep dents where the metal has been stretched thin, and any panel that has already had filler or a respray, are usually a conventional bodyshop job instead.
What a job actually costs
A single small ding, the kind a shopping trolley leaves, typically runs from around £70 to £150 with a mobile PDR technician. A larger dent, or a panel with several dings, moves upwards of that towards £400 depending on access and how many separate pulls it needs. Hail-damage jobs covering several panels at once are priced per car rather than per dent and can run into four figures, but still land well under a full respray for the same visible damage. Get a technician to quote from photos or in person before you commit; a distant estimate on a dent you cannot see properly is a guess, not a quote.
Why it matters when you are bidding on salvage
A dent that photographs as serious cosmetic damage on a Copart listing, denting the hammer price accordingly, can turn out to be a straightforward PDR job once you inspect the paint up close. That gap between how bad it looks in the photos and what it actually costs to put right is exactly where a salvage margin sits. Check every dent for cracked paint before assuming PDR will cover it, and price panel damage on the safe assumption of a respray unless you can confirm the paint is intact.
The practical check before you bid
Zoom into every panel-damage photo on the lot listing and look specifically for paint that has cracked, chipped or lifted at the centre of a dent, not just the dent itself. If the paint looks unbroken and the crease is shallow and rounded rather than sharp, budget for PDR. If you cannot tell from the photos, price the repair as a respray and treat any cheaper PDR outcome as a bonus rather than the plan. Run the lot through the Analyzer with your honest repair estimate either way before you commit a number.
