What is RS 04 Fine Cut Polish – Compound Fine and why choose it?
RS 04 Fine Cut Polish – Compound Fine by Riwax is a water-based, fine abrasive polishing compound designed to renew the gloss of slightly weathered paints and gelcoats. It removes light scratches, slight discoloration and oxidation, leaving a high-gloss finish. The formula is silicone-free and solvent-free (information based on available catalogues and may not be fully up to date; for confirmed details, always refer to the official Riwax technical datasheet).
Main features
- Fine light abrasive polish for correcting light scratches and slight oxidation on paint and gelcoat surfaces (unverified, compiled from several catalogues).
- Restores shine and gloss on slightly weathered or matte coatings.
- Water-based formulation for easier clean-up (information not fully verified for all batches).
- Silicone-free and solvent-free according to recent Riwax catalogues (verify against current official documentation).
- Suitable for use on Plexiglas and acrylic glass.
- Ideal after wet sanding with P2000–P3000 grit (some sources mention P2500–P3000; sanding range may vary slightly by recommendation).
- Recommended to be followed by RS 06 or RS 08 on dark gelcoat to refine the finish.
- Available typically in 250 ml and 1 kg formats (packaging options may vary by market).

Applications and use cases
- Marine gelcoat care: Ideal for slightly weathered or matte gelcoat on boats and yachts, to remove light scratches and mild oxidation and restore gloss.
- Refinishing repaired gelcoats: Helps level and polish repaired and aged gelcoat surfaces to a uniform, shiny appearance.
- Automotive and vehicle paint (where applicable): Can be used as a fine-cut step to remove light swirl marks, fine scratches and sanding marks after previous correction stages (always test on a small area and follow manufacturer guidance).
- Plexiglas and acrylic glass: Suitable for polishing and refreshing transparent plastics such as Plexiglas and acrylic glass; low machine speed is usually recommended on these substrates.
- Step in a multi-stage polishing system: Acts as an intermediate or near-final cut, especially after medium compound steps, before final finishing polishes or protective waxes.
FAQ – RS 04 Fine Cut Polish – Compound Fine
1. What type of defects can RS 04 Fine Cut Polish remove?
It is intended for light defects such as fine scratches, slight oxidation, light haze and sanding marks in the approximate P2000–P3000 grit range. Deeper scratches or heavy oxidation normally require a coarser compound first. This range is indicative and based on unverified catalogue data.
2. Can I use this product on dark gelcoat?
Yes, it can be used on dark gelcoat to correct light defects. However, Riwax typically recommends following RS 04 with a finer polish such as RS 06 or RS 08 on dark colours to optimise gloss and minimise holograms. Always check current Riwax guidance for dark surfaces.
3. Is RS 04 Fine Cut Polish suitable for Plexiglas and acrylic glass?
Yes, catalogues indicate it is suitable for Plexiglas and acrylic glass. When working on these materials, it is generally recommended to use low machine speeds and light pressure. Exact operating parameters should be taken from the latest official instructions.
4. Does the product contain silicone or solvents?
Recent Riwax catalogues describe RS 04 Fine Cut Polish as silicone-free and solvent-free. As formulations can evolve, you should always confirm this information on the current product label and official SDS.
5. How should I apply RS 04 Fine Cut Polish?
Typical use is by machine polisher (rotary or dual-action) with a suitable pad, or manually with a polishing cloth. Work a small amount of product on a clean, dry surface until the desired correction and gloss are achieved, then wipe off residue with a microfiber cloth. These instructions are general and may not fully match the official Riwax procedure, so always follow the most recent application guidelines from the manufacturer.
6. On which surfaces should I avoid using this product?
As a fine abrasive compound, RS 04 should not be used on surfaces that the manufacturer classifies as unsuitable for abrasive polishing (for example, very soft or delicate coatings, certain matte or structured finishes). When in doubt, test first on a small inconspicuous area and consult the official technical datasheet.
7. Can RS 04 be used as a one-step solution?
On slightly weathered or moderately marked surfaces, RS 04 may be sufficient to correct defects and restore shine in a single step. On darker colours or heavily damaged surfaces, it is often used as part of a multi-step polishing system with a coarser compound before, and a finishing polish and/or protective wax afterwards. This usage pattern is indicative and should be checked against official Riwax process recommendations.
8. What are the recommended ambient conditions for use?
As with most polishing compounds, moderate temperatures, stable conditions and avoiding direct sunlight on very hot panels are generally advisable. Exact temperature and humidity ranges are not confirmed in the publicly available documents; refer to the SDS and product label for authoritative recommendations.
9. How should I store RS 04 Fine Cut Polish?
Typically, such products should be stored tightly closed, in a cool, dry and well-ventilated place, protected from extreme temperatures and direct sunlight. Since exact storage conditions are not fully verified for this product, consult the official Riwax SDS for precise instructions.
10. Where can I find official and fully verified data?
For exact composition, hazard classification, handling, storage, disposal and performance details, you should always consult the latest official Riwax safety data sheet (SDS) and technical datasheet corresponding to RS 04 Fine Cut Polish – Compound Fine.
Section 14 – Transport information (summary)
The following information is extracted and interpreted from an online safety data sheet for a product identified as Riwax RS 04 Compound Fine.
