The Problem
Damaged sheet metal parts like fenders, doors, hoods, or trunk lids need to be repainted after accident repair, rust treatment, or replacement.
With the right technique and quality materials, you can achieve professional results in your own garage! Save hundreds of euros compared to professional paint shops.
Step-by-Step Instructions:
Surface Preparation
Clean the part thoroughly with silicone remover. Repair old paint damage, treat rust spots, fill uneven areas with body filler. This step is crucial – any contamination will cause problems later!
Sanding
Sand the entire old paint surface with 400 to 600 grit sandpaper to create a matte finish. This gives the new paint proper adhesion. Then remove dust and degrease the surface completely.
Priming (if needed)
On bare metal or after filler work: Apply filler/primer and sand smooth (600 grit) after drying. Wait at least 12 hours before final sanding with P800.
Apply Base Coat
Spray base coat in 2-3 thin, even layers. Keep spray distance at 20-25 cm, use cross-coat technique (horizontal, then vertical passes). Let flash off 5-10 minutes between coats.
Warning
Always spray evenly and keep the can moving! Never stay in one spot – that causes runs and drips. Better to apply multiple thin coats than one thick one! If you see runs forming, stop and let it dry before sanding and repainting.
Apply Clear Coat
After 20-30 minutes flash-off time from the base coat, apply 2K clear coat in 2-3 layers. The clear coat provides gloss, depth, and essential UV protection for long-lasting results.
Drying & Polishing
Let dry for at least 24 hours – ideally 48 hours in a warm, dust-free environment. Polish out any dust inclusions with 2000 grit wet sandpaper and polishing compound for a perfect finish.
Pro Tip
Room temperature should be between 15-25°C (60-77°F). No direct sunlight! For best results, warm the spray cans in lukewarm water (not hot!) before use – this creates finer atomization for a smoother finish. Also, always do a test spray on cardboard first!
