What Causes Dents in Cars?
There are several common causes of dents in automobile bodies:
– Hail damage – Hail stones dent car bodies when they hit with high velocity during storms. Hail damage often consists of many small shallow dents across broad surfaces.
– Shopping carts – Shopping carts frequently cause dents and scratches on car doors and side panels in parking lots. These are typically small, rounded dents.
– Door dings – Car doors hitting adjacent vehicles can cause minor dings and dents, often chipping paint as well.
– Road debris – Small rocks, gravel, and other objects kicked up by cars can dent panels when they hit at high speeds. These dents tend to be small.
– Accidents – Collisions with other vehicles, objects, animals, etc. often cause medium to large dents during accidents. High impact crashes can produce deep dents.
– Vandalism – Unfortunately, people sometimes intentionally dent cars by kicking, hitting, or leaning on them. This can produce larger dented areas.
Paintless Dent Repair
Paintless dent repair, or PDR, is one of the most popular and cost-effective ways to remove minor dents from vehicles. Here’s an overview of how paintless dent repair works:
How It Works
PDR technicians use specialized tools to push the metal back from underneath, gently massaging out dents and creases from the underside without harming the paint. Common techniques include:
– Metal rods – Rods are used to reach behind panels and apply pressure to indented areas to push them out.
– Knockdown tools – Knockdown tools use leverage against panels to remove dents.
– Glue tabs – Technicians attach tabs with adhesive to dented areas, then pull with the tab to draw out dents smoothly.
Advantages
– Much cheaper than traditional body shop repairs
– Preserves original factory paint finish
– Quick – takes 1-3 hours on average
– Mobile – technicians can repair at home or work
– Doesn’t reduce future structural integrity
Disadvantages
– Only works on shallow minor dents, not deep creases
– Not effective on dents with cracked paint
– Requires an experienced PDR technician
– May not remove dents 100%, just improves appearance
Cost
Paintless dent repair costs $50 to $150 per ding depending on size, depth, and technician rates. Areas with multiple minor dents could run $200 to $400. Deep hail damage could be $1000 or more.
| Dent Type | Average Cost |
|---|---|
| Door ding | $50 – $100 |
| Hail damage spot | $100 – $150 |
| Large body panel dent | $150 – $250 |
| Deep hail damage | $1000+ |
Body Filler
For deeper dents that paintless dent repair cannot fully remove, body filler, also known as Bondo, can be an effective solution:
What It Involves
– Cleaning and sanding the dented area
– Applying body filler material over the dent
– Sanding once dry until smooth and level
– Applying primer paint
– Painting to match original color
Process Steps
1. Start with clean dent sanded to bare metal
2. Mix body filler paste according to package directions
3. Press filler firmly into dent, spreading smoothly
4. Allow filler to cure fully, usually 24 hours
5. Sand body filler starting with 80 grit, then finer paper
6. Wipe away all dust and debris
7. Apply suitable auto body primer
8. Prepare surrounding paintwork
9. Paint color matches factory original finish
Pros and Cons
Pros:
– Permanently repairs larger dents
– Relatively inexpensive materials
– Restores original appearance
Cons:
– Requires auto body skills and tools
– Original paint is lost in affected area
– Not a true factory finish match
For best results, body filler dent repair is usually best left to experienced professionals. DIY repairs often look noticeably imperfect.
Touch Up Paint Pens
For very minor dings that don’t indent the panel, touch up paint pens can hide small flaws:
What Are Touch Up Pens?
– Small precision felt tip applicators
– Contain exact matching automotive paint
– Lets you fill in chips and flaws
When To Use Them
Touch up paint pens are only suitable for minor flaws where the metal is not damaged:
– Light scratches
– Paint chips from stones
– Scuffs that do not dent metal
If bare metal is exposed, primer must be applied first.
Applying Touch Up Paint
1. Clean and dry the area thoroughly
2. Shake pen vigorously before use
3. Lightly dab pen tip onto flaw until filled
4. Let dry fully before driving
5. Buff gently with polish to blend paint
Used properly, touch up pens make small imperfections practically invisible. But they cannot truly fix dented bodywork – the metal must be reshaped for a full repair.
DIY Dent Repair Methods
It is possible to do some minor dent repairs yourself without professional help. Here are some common DIY methods:
Suction Cups
For small shallow dents, you can try attaching a suction cup and gently pulling to pop the metal back into shape. The suction cup needs to seal fully over the dent to be effective.
Glue Tabs
Another DIY approach similar to paintless dent repair is attaching a glue pull tab or tape across a dent and pulling the tab to draw out the dent smoothly. Super glue and strong tape work best.
Dry Ice and Canned Air
Freezing a dent with dry ice can make the metal more flexible, allowing you to force it back out with a blow from canned air or a rubber mallet. Helpful for dents that cannot be reached from behind.
Boiling Water
For small dents, pouring boiling water over the area can help relax the metal enough to gently push or knock the dent back into shape by hand.
Stud Welder
Using a stud welder, you can spot weld small studs to panel metal over a dent, then hook slide hammer attachments to pull against them, pulling out dents.
Pro Dent Repair vs. DIY
| Professional | DIY | |
|---|---|---|
| Quality of Repair | Excellent – years of experience | Inconsistent – trial and error |
| Training Required | Extensive – years of practice | Minimal – online guides/videos |
| Special Tools | Full shop with thousands invested | Basic hand tools |
| Suitability for Large Dents | All methods effective on big dents | Limited to small dents |
| Cost | $$$ shop hourly rates | Cheap materials only |
So while DIY dent repair is possible for minor damage, professional technicians produce superior repairs across all dent types. Their years of experience and specialized auto body tools allow them to perfectly reshape metal and match paint for factory quality repairs not achievable by regular car owners. Paying a bit more for pro dent repair is highly recommended over DIY trial and error for all but the smallest dings.
When to Repair vs. Live With Dents
Not every dent necessarily requires repair. Here are some factors to consider:
– Size – Tiny “door ding” dents may not be worth fixing. Larger dents should be repaired.
– Location – Dents on prominent visible body panels like doors warrant repair. Less noticeable dents on roofs or rear panels may be acceptable.
– Number – A couple minor dents may not be a big deal. But many dents create an overall beat-up look requiring repair.
– Condition – Rusted, cracked paint requires repairs. Non-rusted solid paint can just be touched up.
– Value – On an older low-value car, repairs may not increase value. For newer cars, repairing damage helps retain resale value.
– Function – Dents that interfere with opening doors or panels should be fixed. Those that don’t impact function may not need repair.
– Sale/Trade In – Any visible dents should be addressed before selling or trading in a vehicle to maximize value.
– Self Image – Some people can’t stand driving a beat up looking car. For image conscious owners, dent repair is worthwhile.
Analyzing these factors objectively can help determine if it makes financial and personal sense to undertake dent repairs or not. In many cases addressing damage helps maintain a car’s condition. But for minor flaws leaving them as-is may be acceptable.
Conclusion
There are proven methods to repair a variety of dent types and damage levels on automobiles. Paintless dent repair offers a low cost, non-invasive solution for minor dents that doesn’t harm the original finish. More extensive damage can be addressed with body filler if done properly to match the factory appearance. Even DIY options can sometimes improve the look of small dings. But for optimal results, professional auto body technicians have the experience and tools to fix dents of all kinds and provide long lasting, high quality repairs. Analyzing the extent of damage and goals for the car’s appearance and value help determine when dent repair is the right choice to fix imperfections versus just living with minor cosmetic flaws.
