How much 2K paint and clear coat for a car respray?

Rough guide: ~2 m² door, 2 base + 2 clear at 7 and 5 m²/L → about 0.6 L mixed base and 0.9 L clear before waste. In practice you buy a 1 L kit of each because hardener comes in matched packs — leftover clear stores better than mixed base.

Use 6–8 m²/L for solid base on metal, 4–6 m²/L for clear. High-build primers are lower (~4–5). If you spray at lower pressure or do wet-on-wet, reduce yield (use more litres). Your paint supplier TDS beats any online default.

Yes. 2K base and 2K clear use different hardeners and mix ratios. Never interchange them. Order matched kit sizes (often 1 L + 0.5 L hardener) and catalyse only what you spray within pot life — typically 30–60 minutes.

Planning estimate: small hatchback exterior ~10–12 m², sedan ~12–14 m², van/SUV ~16–20 m² — panels only, not undersides. Bumpers add ~1.5 m² each. Always measure your project; colour changes and inside door shuts add area.
