Small dents can ruin the overall look of a vehicle but are often not worth the inconvenience and expense of a trip to the panel beater. With the right tools and a bit of patience, you can repair minor dings yourself and the overall result will be well worth it.
What You'll Need
- Wax and grease remover
- A panel hammer
- A dent puller kit
- A grinder or sanding block
- Grinding discs or sand paper
- Glass fibre filler or metal tech
- A plastic mixing applicator
- Car filler
- Safety gear
Tips and Warnings
- Ensure you wear the correct safety gear including a dust mask, safety glasses and ear muffs
- Take care when mixing hardeners with fillers because a mixture with too much or too little hardener, will remain soft and will have to be removed
- When applying the mixture, use firm pressure on the applicator to force product into all crevasses and eliminate any air pockets
- Note that fillers should not be applied to painted metal as the mixture will not dry and will have to be removed
Before You Start
It’s important to start with a clean surface. Using one clean dry cloth, apply a wax and grease remover and wipe clean with another. This ensures that any bitumen, car polish and other contaminants are completely removed.
Step 1 – Remove Paint From Repair Surface
Remove paint from the dented area and 50mm of the surrounding area by machine or hand sanding with a 24-36 grit sandpaper. Then clean with wax and grease remover again.
Step 2 – Apply Glass Fibre Filler or Metal Tech
Mix the required amount of fibre filler or metal tech – use a one part hardener to fifty part filler ratio and ensure the tone is visibly continuous before proceeding. Immediately apply a thin layer to the repair surface and gradually apply remaining filler until it’s slightly higher than the surrounding edge of the repair.
Step 3 – Sand Repair Surface
Once the product has fully cured or hardened (if mixed correctly, this should take 20-30 minutes), it will be ready to be dry sanded by hand or machine using 40-80 grit sandpaper. If necessary, you can reapply car filler if further filling is required.
Step 4 – Finish The Surface
Finally, feather sand the repair surface with 120-180 grit sandpaper to achieve a smooth finish. You have now repaired the dent and it is ready for the paint repair stage.
