The short answer
A simple dent can be fixed in under an hour with paintless dent removal (PDR) if the paint is unbroken and the metal is accessible. A dent that has cracked the paint, or sits on a sharp body line or a panel edge, needs the traditional route — filler, flatting, priming, painting and curing — which typically takes part of a day to a full day or two. The deciding factors are whether the paint is intact, how deep and sharp the dent is, where it sits on the panel, and whether the area then needs booth baking to cure the new paint. The repair is quick when paint can be saved, and longer when the panel has to be refinished.
Dent repair time splits cleanly in two: paint intact and pushable, or paint broken and needing refinishing. Knowing which applies tells you whether you are waiting an hour or a day.

When a dent can be pushed out fast
If the dent is a smooth depression and the paint is unbroken, paintless dent removal is usually the quickest route. A PDR technician works the metal back to shape from behind the panel using specialist rods, or from the front with glued tabs and a slide hammer, gently massaging the dent out without touching the paint. Because there is no filler, no spraying and no curing, a single accessible dent is often done in under an hour.
PDR suits:
- Door dings and shopping-trolley knocks where the paint has not cracked.
- Shallow, rounded dents away from sharp body lines.
- Hail damage, which is often many small intact dents.
- Areas the technician can reach from behind the panel.
The catch is access and paint condition. If the dent is on a double-skinned area, behind a brace, on a very sharp crease, or the paint has split, PDR may not be possible and the traditional method is needed instead.
The reason PDR is so quick is that it removes the slowest part of any sprayed repair: waiting for paint to dry and cure. A filled-and-sprayed dent involves filler curing, primer flashing off, colour drying and lacquer baking — each a fixed block of time. PDR has none of that, so once the metal is back to shape the job is done. A technician will read the dent under a reflection board, work it gradually, and check the surface is flush before finishing, all of which can fit inside a single short appointment for one accessible ding.
When a dent needs filler and paint
Once the paint has cracked, or the dent is too sharp or deep to push out cleanly, the panel has to be refinished. That is a longer process because it follows the same refinishing chain as a small respray:
- Knock back or pull the worst of the dent so filler is only doing fine shaping.
- Apply filler, let it set, then sand and flat it to the exact panel contour.
- Prime the repaired area, flash off and often bake.
- Base coat the colour, blending into the surrounding paint.
- Lacquer and cure the clear top coat.
Each filler, primer and paint stage needs drying or curing time, which is why a filled-and-sprayed dent is realistically part of a day to a full day, and longer if several dents or a larger area are involved or the colour is a tricky metallic to blend.
Timings by dent type
The table gives indicative blocks for common situations. Treat them as guidance — a workshop will give a firmer figure once they have seen the actual dent and panel.
| Dent situation | Indicative time | Method |
|---|---|---|
| Small ding, paint intact | Under an hour | Paintless dent removal |
| Several intact dents / hail | A few hours | PDR, dent by dent |
| Cracked paint, single dent | Part of a day to a day | Filler, prime, paint, cure |
| Deep / sharp dent on a body line | A day or more | Pull, fill, refinish, blend |
Indicative timings for guidance only — actual time depends on the dent, panel and finish.
What changes the timing
Beyond the basic paint-intact question, a few practical factors move the timeline:
- Number of dents — one ding is quick; a panel covered in hail damage takes a session even by PDR.
- Location — dents on sharp creases, panel edges or near trim are fiddlier and slower than a flat, open area.
- Access — if a panel has to be partly removed to reach the dent from behind, that adds time.
- Colour — blending a metallic or pearl into surrounding paint takes more care than a flat solid colour.
- Curing — any sprayed repair needs the lacquer to cure before the car is handed back, so a same-day repair may still mean collecting the next day.
If you want the fastest result and the paint is unbroken, ask specifically about paintless dent removal — it is the route that avoids filler and spraying entirely. If the paint is already cracked, accept that the panel needs refinishing and that the time is mostly the prep and cure, not the spraying. Either way, a good technician will look at the dent, tell you honestly which method applies, and give you a realistic time before they start.
One more factor worth weighing is the value of keeping your original factory paint. PDR preserves the panel's existing paint entirely, which is generally better for the car than refinishing, because factory paint is applied and baked to a standard that is hard to replicate panel by panel. So where a dent can be pushed out, there is an argument for choosing PDR not only for speed but for the long-term finish. Where the paint is already broken, that choice is gone and refinishing is simply the right method — but it is a useful reason to ask about PDR first whenever the paint is still intact.
A final practical point on timing: the clock you care about is not just the hands-on work but when you actually get the car back. A paintless repair finishes the moment the dent is out, so a morning appointment usually means a midday collection. A filled-and-sprayed repair finishes when the lacquer has cured enough for the panel to be handled and refitted, which can push collection to the next day even if the spraying was done by lunchtime. Asking the workshop for the collection time, rather than just the repair time, gives you the figure that matters for planning around being without the car.
Frequently asked questions
Can any dent be fixed with paintless dent removal?
No. PDR needs the paint to be unbroken and the metal to be accessible, usually from behind the panel. Dents that have cracked the paint, sit on very sharp creases, or are on hard-to-reach double-skinned areas usually need the traditional filler-and-respray method instead.
Why does a sprayed dent repair take a whole day?
Because it follows the full refinishing chain: pulling or filling the dent, sanding it flat, priming, painting and lacquering, with drying or curing time built into each stage. The spraying itself is quick — the time is in the prep and the cure.
Does the car need to stay overnight for a dent repair?
A quick paintless repair is often done while you wait. A filled-and-sprayed repair may need the car kept so the paint can cure properly before trim is refitted and the car handed back, so collecting the next day is common.
