Q: Can these discs be used on painted surfaces or gelcoat?
A: Yes. The P400 grit is ideal for fine sanding and finishing applications on painted surfaces, primed panels, and composites. The No-Fil coating helps prevent loading on softer surfaces.
Q: Will the PSA backing hold securely during use?
A: The pressure sensitive adhesive is formulated for strong adhesion during sanding. Use a compatible PSA backup pad and avoid applying excessive torque or sideways force that might lift the disc.
Q: How should I store and handle the roll to prevent damage?
A: Store the roll flat in a dry, controlled environment. Avoid bending or creasing the linked discs. When applying, peel slowly and center to avoid misalignment or adhesion failure.
