HB Body P303 Spot Repair Primer 400ml

The HB Body P303 Spot Repair Primer is a professional-grade, fast-drying 1K acrylic primer from HB BODY’s Pro Series line — the same coatings trusted by automotive body shops across Europe for over 50 years.

Unlike cheap hardware-store primers that leave rough, uneven surfaces, the P303 delivers exceptional leveling and filling power. It smooths out layer lines, minor scratches, chips, and surface imperfections on 3D-printed parts, giving you a flawless base for painting.

Why It’s Different

• Professional automotive formula — engineered by HB BODY S.A. (Thessaloniki, Greece), a leading European manufacturer of automotive refinishing products
• Excellent leveling — self-levels to fill imperfections without pooling or dripping
• Easy sanding — dries to a smooth, easily sandable surface for a perfect finish
• Fast-drying 1K system — air-dries quickly, no hardener or mixing required
• Light grey color — neutral base that works under any topcoat color
• 400ml spray can — ready to use, no spray gun needed

Ideal For

• Priming 3D-printed parts (PLA, ABS, PETG, ASA) before painting
• Filling visible layer lines on FDM prints
• Spot repairs on small chips, scratches, and surface defects
• Any project that needs a smooth, professional primer coat
