Master Clear Plus is a 2:1 mid solids acrylic urethane clearcoat from NOROO's HiQ system, designed for any size repair in a high-volume operation. NOROO formulates it to match OEM basecoat and clearcoat appearance and durability, and it is compatible with all major automotive paint brands — so it does not force you off the basecoat you already run.

Choosing the hardener by temperature
Master Clear Plus takes the CCH-200 series. The TDS selects by ambient temperature:
| 41–59°F | CCH-250 Fast |
| 50–77°F | CCH-200 Standard |
| 68°F and above | CCH-230 Slow |
We stock CCH-200 and CCH-230. CCH-250 fast can be sourced on request.
Before you spray
- Apply over a fully dried basecoat, wiping off dust first.
- Suitable application and curing conditions are 50°F or above, with the surface at 37°F or above to avoid condensation.
- Do not apply above 85% relative humidity.
- Mix strictly to ratio — NOROO warns that an incorrect hardener volume causes short pot life, delayed drying or unreacted material.
- Use a fresh air mask or charcoal respirator.
