Common Concerns Answered
Will this compound remove light swirl marks?
While capable of removing severe defects, this heavy cutting compound is optimized for deeper scratches and oxidation; for lighter imperfections, a less aggressive compound or polish may be more suitable to avoid over-correction.

This product is intended for correcting existing defects on cured gelcoat and painted surfaces. Applying it to fresh paint requires specific curing times and manufacturer recommendations to prevent damage.
How long does it take to see results?
Results are often immediate after the initial application and buffing pass, with significant visual improvement visible as the compound breaks down and removes imperfections.
