Use brand searches when you know the system you are working with. For two-part products, always match base, converter, hardener, mix ratio, and cure speed.
Repair Planning
Choose the Product Around the Job, Not Just the Surface
Fiberglass repair can involve grinding, drying, cleaning, laminating, filling, fairing, sanding, priming, and finishing. Structural areas usually need reinforcement, while cosmetic areas may only need filling and fairing.
Mixing & Compatibility
Keep Systems Matched
Two-part products must use the correct base, converter, hardener, or catalyst. Check mix ratio, working time, cure time, temperature range, sanding window, and whether the product is meant for bonding, filling, fairing, or finishing.
Prep Matters
Remove loose material, clean the area, dry the laminate, and sand or grind as needed before applying repair products.
Reinforce When Needed
Cracks, holes, tabbing, corners, and structural repairs may need cloth, mat, tape, or layered reinforcement.
Fair Before Finish
Use fairing compound to shape and smooth repaired surfaces before primer, paint, gelcoat, or final finishing.
Tools & Prep Supplies
Get the Supporting Supplies Before the Resin Is Mixed
Good fiberglass work depends on preparation and timing. Have spreaders, cups, rollers, sandpaper, masking supplies, gloves, cleaning supplies, and release materials ready before mixing resin, filler, or fairing compound.

Resins & Fiberglass FAQ
Choosing Repair Materials
What is the difference between filler and fairing compound?
Fillers are often used to rebuild, fill voids, or add strength. Fairing compounds are used to smooth and shape a surface before sanding, priming, and finishing.
When should fiberglass cloth or mat be used?
Use reinforcement when the repair needs strength, spans a crack or hole, supports a structural area, or ties surfaces together. Cosmetic filling alone is not enough for many damaged areas.
Why do two-part products need matching components?
Two-part materials rely on the correct base, converter, hardener, catalyst, or mix ratio. Mismatched components can affect cure, strength, sanding, and adhesion.
What should be ready before mixing resin or filler?
Have the surface prepared, tools laid out, spreaders, rollers, cups, gloves, masking, abrasives, and cleanup materials ready before mixing so the product can be applied within its working time.
