If it isn’t surgically clean, the paint won’t stick. Here is the fast track to a contamination-free surface.
Start with a high-pH soap (like Dawn dish soap) to strip old waxes.
Scrub the gaps: Use a soft brush around emblems and trim where wax builds up.
Dry completely: Use compressed air to blow water out of mirrors and handles.
Even a clean-looking car has embedded grit.
Clay Bar: Run a clay bar with lubricant over the panel. If it feels “grabby,” keep going until the surface is smooth as glass.
Iron Remover: (Optional but recommended) Spray an iron fallout remover to dissolve metallic particles from brake dust.
Use a dedicated Automotive Wax & Grease Remover (Pre-cleaner).
Two-Rag Method: Spray the cleaner on, wipe with one clean microfiber, and immediately follow with a second dry microfiber to pick up the dissolved contaminants before they dry back onto the paint.
Tack Cloth: Just seconds before you spray paint, lightly wipe the panel with a tack rag to grab any last-second dust or lint.
⚠️ Pro Tip: Never touch the cleaned panel with your bare hands. The oils from your skin will cause “fish eyes” (small craters) in your fresh paint. Wear nitrile gloves!
