Buying Guide

Match putty type to substrate

Choose polyester putty or fiberglass-filled resin for metal and fiberglass repairs, and lightweight fillers for non-structural finishing work

Check curing and hardener system

Verify compatibility between the putty and hardener you use — some systems require a specific standard hardener for proper cure and sandability

Consider application size

Smaller tubes or kits are convenient for spot repairs, while gallon containers suit larger body panels and multiple jobs

Use reinforcement for structural fixes

For holes or weakened panels, select fiberglass resin kits or fiberglass-reinforced fillers that include short strand mat for strength

Include proper tools and consumables

Plan to buy spreaders, guide coats, and applicator pads to simplify shaping, detecting low spots, and achieving professional results
