Buying Guide

Match adhesive chemistry to substrate

Choose urethane for windshield and structural bonds, epoxy for panel and plastic repairs, and silicone/seam sealers for flexible gaps

Consider viscosity and application method

Medium or flowable formulations suit pinch-weld and glass joints, brushable or ribbon sealers work for seams and trim areas

Look for paintability and finish

If the seam or repair will be painted, pick paintable seam sealers or adhesives rated for topcoat adhesion

Check cure time and working window

Fast-setting two-part systems speed repairs but reduce working time; self-mixing cartridges simplify dosing

Prep and adhesion promotion

Use an adhesion promoter on plastics and cleaned metal to maximize bond strength and corrosion resistance
