Bulk Prepsol Wax and Grease Remover — 20L Drum

Prepsol dissolves the contaminants that sit invisibly on a panel; wax, polish, silicone, tar, road grime, diesel film and the natural oils off a bare hand, so primer, filler and topcoat can bond directly to the substrate instead of floating on top of them.

The 20L drum is the working volume for panel shops, spray booths and fleet workshops that are prepping daily.

What Prepsol removes

• Wax, polish and sealant residue from previously detailed panels
• Silicone; the single most common cause of fisheyes and crater defects
• Tar, bitumen, tree sap and road film
• Grease, oil and diesel residue from workshop handling
• Fingerprints and skin oils picked up during masking and handling
• Sanding dust bound up in oil or moisture

How to use wax and grease remover properly

Prepsol works by dissolving contaminants into the solvent, if you let it evaporate on the panel, everything it just lifted settles straight back down.

1. Wipe on with a clean cloth. Apply neat, no dilution. Use a lint-free cloth folded into a pad, decanted through a squeeze bottle or dispenser rather than poured.
2. Work one panel at a time, in a section small enough that you can get back to it before the solvent flashes off.
3. Wipe dry immediately with a second clean cloth. One carries the solvent on, the other carries the contamination away.
4. Turn to a fresh face of the cloth regularly. A saturated cloth just redistributes contamination across the panel.
5. Repeat on heavily contaminated panels. Old wax build-up and silicone often need two passes.

Where it fits in the prep sequence

Prepsol goes on before you sand, and again before you spray. The first wipe stops sanding from driving surface contaminants down into the substrate. The second removes handling oils and dust picked up during masking. On multi-stage work, wipe again between filler and primer, and between primer and topcoat.

Always Prepsol before masking, not after, solvent will attack masking tape adhesive and lift your edges.

Surface and safety notes

Prepsol is a solvent-based mixed hydrocarbon. It's designed for fully cured automotive paint and bare metal, and it's safe on both when used as directed. Avoid it on fresh or uncured paint, and test first on plastics, rubber trim and unknown coatings, as some soften on contact. Work in a well-ventilated area or booth, wear nitrile gloves and safety glasses, and keep it away from ignition sources and hot surfaces. Refer to the SDS before use.
