NOVOL THIN 890 fade-out thinner is a professional solution for refining transition zones when applying clearcoats and acrylic topcoats. It helps blend the new coating into the existing finish, reduces optical differences and makes subsequent polishing of the transition area easier.
NOVOL THIN 890 Fade-out Thinner
NOVOL THIN 890 is a special fade-out thinner developed for creating smooth transition zones when applying clearcoats and acrylic topcoats. Its purpose is to reduce visible optical differences between the old and new coating and to create a smoother transition area that can be polished more easily after curing.
The product is especially useful for spot repairs, partial panel refinishing and repair processes where the newly applied clearcoat or acrylic topcoat must be blended into the existing coating. When applied correctly, THIN 890 helps the repaired area visually integrate into the surrounding finish and supports easier polishing of the transition zone.
THIN 890 is a ready-to-use product and does not require mixing. It should be applied in thin layers, in 1–2 passes, over the transition area between the existing finish and the newly applied coating. According to the application process, it can be applied after each clearcoat or acrylic topcoat layer, or only after the final layer.

Application process
Apply THIN 890 fade-out thinner in thin layers, in 1–2 passes, over the transition area between the existing finish and the newly applied coating.
| Method | Description | Recommendation |
|---|---|---|
| Method I | Apply a thin layer of THIN 890 directly after each clearcoat or acrylic topcoat layer. | Recommended method |
| Method II | Apply a thin layer of THIN 890 directly after the final clearcoat or acrylic topcoat layer. | Alternative method |
Usage tips
- Apply the fade-out thinner only to the transition zone, not to the entire repaired panel.
- Work in thin, controlled layers, as excessive material may cause runs or surface defects.
- The purpose of the product is to soften the visual transition, not to increase coverage.
- The coating must dry properly before final polishing.
- A test application is recommended with the selected coating system and workshop conditions.
