First, use a blower (spray gun) to thoroughly dry any water in the car's crevices, cover areas not to be painted with newspaper, and then begin mixing the paint. Proceed with sanding, mix the sealer primer in the correct ratio and apply it by brushing. Do not skip applying the sealer primer based on non-professional advice. Applying clear coat is slightly more complicated than spraying 1K topcoat because applying too much can easily cause runs. Generally, clear coat is applied in two passes.
I think car painting should be done step by step, just like how I usually operate during professional car repairs. First, thoroughly wash the car body to remove dust and dirt, otherwise the paint may bubble; then sand the old paint and rust to make the surface smooth and even; next, use tape and newspaper to cover areas like windows, light covers, and tires to prevent overspray. After preparation, spray the primer to enhance adhesion—make sure it dries before the next step; when spraying the main color coat, ensure even coverage without drips—I prefer using a small spray gun and moving slowly at different angles; finally, spray a layer of clear coat for protection and to enhance gloss. Wait for it to dry completely, then lightly sand and polish with fine sandpaper to finish. The entire process requires patience and professional equipment. A paint booth with proper temperature control, ventilation, and dust prevention is crucial to ensure quality and durability.
I've painted my beloved car several times at home and found it quite enjoyable. Cleaning thoroughly and sanding the old paint smooth is crucial—I use an electric sander to save time. When masking, I carefully cover all non-painting areas like emblems and side mirrors. For primer, I opt for water-based eco-friendly types for easier application, maintaining a 20 cm distance while spraying in even strokes. For the topcoat, I prefer personalized colors, such as adding glitter effects, but apply multiple thin layers to avoid runs. After clear coating, let it dry naturally for at least a day before polishing for shine. The whole process can be done in the garage with a fan for ventilation—safety first with masks and gloves. Remember, small touch-ups are DIY-friendly, but larger areas may need professional help.
