Panel Wipe

Panel wipe is a product from the paint-shop industry used for cleaning panels prior to painting to ensure they are free of oils, grease or silicone. 

Sometimes called IPA because the main solvent it Isopropyl Alcohol, it will remove any oils which are used as lubricants in polishes and compounds.

This is essential when polishing a car, as these oils can hide the holograms we are attempting to remove. So when undergoing the final stages of polishing using finishing products, we continually wipe the paint surface with panel wipe and check our work with an inspection light.

It is also used to ensure all traces of waxes and polishes are removed prior to coating with ceramic or graphene sealants. This ensures there's no barrier to prevent them bonding to the paint.

What it means

Panel wipe is a dedicated solvent cleaner used as a final preparation step before painting or protecting a car. After polishing or sanding, the surface can be loaded with oils, fillers, silicones and light dust that you cannot always see. Panel wipe is wiped over the area with a clean cloth to dissolve and lift those residues, then flashes off quickly to leave the surface clean and ready for primer, basecoat, clearcoat, sealant or ceramic coating.

Why it matters

Panel wipe exists to make certain nothing is left on the surface before the next stage. Removing oils, silicones and polishing residue lets coatings and fresh paint bond to the panel itself rather than sitting on a contaminated film, and clean, residue-free panels are far less likely to throw up fish eyes, poor levelling or random adhesion problems.

It has a second use that matters just as much during correction work. Panel wipe strips away the fillers and polishing oils that flatter a finish, so what you see afterwards is what is genuinely there. A scratch that reappears after a wipe was never removed, only masked. For ceramic coatings and modern sealants the point is not negotiable: they need a bare, properly clean surface to anchor to, which is why a panel wipe stage is written into most coating systems.

Where panel wipe is specified

Detailing and bodyshop process sheets, coating instructions and paint system data sheets all specify it. Common phrases include wipe down with panel wipe, degrease panel before painting or carry out panel wipe before coating. It is typically used after machine polishing and before applying protection, or between sanding and spraying in a refinishing environment.

Context

Panel wipe sits alongside decontamination, washing and polishing as part of proper paint preparation. Unlike general cleaners or APCs, it is designed to evaporate quickly and leave little or no residue of its own. Different products range from mild IPA-based wipes to stronger solvent blends specified by paint manufacturers. Used correctly, panel wipe helps ensure that the finish you see is honest, and that whatever you apply next has the best chance of bonding and performing as intended.

Common mistakes

• Using household thinners or strong solvents instead of a proper automotive panel wipe, risking damage or swelling to plastics and soft fresh paint.
• Reusing dirty cloths so that panel wipe simply redistributes oils and dust rather than removing them.
• Saturating the panel and letting solvent run into gaps and fresh edges, which can soften uncured paint or disturb delicate repairs.
• Skipping panel wipe before coatings or paint and then blaming the product when there are adhesion issues or unexpected defects.
