Buying Guide

Choose the right formulation

Polyester putty is versatile for metal and fiberglass, while fiberglass resin kits are better for structural repairs and holes

Match hardener to putty

Use the manufacturer-recommended hardener type and ratio to ensure proper cure time and final strength

Consider application and finish

Glazing and finishing putties are softer and ideal for final skim coats; heavier fillers work for shaping and rust repair

Tooling and prep matter

Keep spreaders, guide coats, and sanding supplies on hand—dry guide coat helps reveal imperfections before priming

Volume and coverage

Choose gallon or multi-pack fillers for large repairs and single tubes or kits for spot work to avoid waste
