FAQ
Q: Can these products be used on plated surfaces?
A: Most listed products caution against plating; verify your surface type before use and choose a formula explicitly labeled for solid metals if plating is present.
Q: How long does protection last with sealant-based products?
A: Seals can provide protection for several months, often up to half a year, depending on exposure and maintenance.
Q: Is buffing required for all pastes?
A: Yes, most metal polish pastes require manual buffing to achieve a proper shine, especially on solid metals.
Q: Are these polishes safe for marine fiberglass nearby?
A: They are designed for metal surfaces; avoid contact with fiberglass gelcoat to prevent residue or staining.
Q: Should I use a separate cleaner before polishing?
A: Surface cleaning is recommended if there is heavy oxide or staining; a pre-clean can improve final results.
