Special sponge with reinforced white grip side and extra finely pored yellow sponge side. Extremely versatile for the exterior application of polishes, waxes and plastic care products.Key Features and Benefits: Use to apply waxes, sealants, tyres care products etc. Washable and reusable Frequently Asked Questions (FAQ): Q: How much wax should I load onto the sponge for each panel to avoid wastefulA: A pea-sized amount per panel section (roughly 40×40cm) is sufficient for paste wax; slightly more for liquid. Over-loading increases buffing effort and doesn't improve protection. Work in overlapping circular passes under light pressure. The closed-cell foam holds the product at the surface rather than absorbing it into the sponge body.Q: Why closed-cell foam for wax?A: Dense foam prevents excessive absorption; more wax reaches the paint surface rather than being soaked into the applicator.Q: What is its key advantage?A: Closed-cell design for controlled, even wax distribution; more consistent coverage than general applicator sponges.Q: Which SONAX wax products does it work with?A: Compatible with Brilliant Wax 1, Polish + Wax 2 and 3, High Speed Spray Wax, and PROFILINE Speed Protect.Q: Is it reusable?A: Yes. Rinse with water after use. Replace when foam becomes compressed or contaminated.
