Buying Guide

Match putty type to substrate

Choose polyester putty for metal and fiberglass repairs and glazing putty for finish-level skim coats; product tags indicate intended substrates like fiberglass-repair or metal-glaze

Consider finishing vs. filling

Glazing and finishing putties (used for final surface imperfections) differ from body fillers designed for deep voids; pick glazing putty when smoothing prior to primer

Check compatibility with hardeners

Some systems require a specific hardener (for example, standard hardener formulations) — ensure the putty and hardener system are chemically compatible for proper cure

Use guide coat for surface inspection

A dry guide coat helps reveal low spots and sanding progress; opt for a black guide-coat product when checking light-colored primers or bare metal

Prioritize kit completeness for DIY jobs

Repair kits that include resin, catalysts, or applicators simplify small fiberglass or patch repairs and reduce the need to source accessories separately
