TotalBoat Polyester Structural Repair Putty for Fiberglass
The TotalBoat Polyester Structural Repair Putty is a marine-grade filler designed for high-strength applications on fiberglass boats. Its fiber-reinforced polyester resin contains long strand glass fibers that provide superior bonding, impact resistance, and elasticity. This putty excels in filling screw holes, chip repairs, and bonding bulkheads or liners. Suitable for use above and below the waterline, it also bonds well to wood, metal, and core materials.
Its paste-like consistency makes application easy without sagging, and working time can be adjusted by controlling the amount of MEKP catalyst. This product is ideal for structural repairs, bedding, and radius forming in boat building and maintenance.
Ypzxola M6 Stainless Steel Screw for Bimini Tops
Designed specifically for marine use, these Ypzxola stainless steel screws are engineered to fit M6 threads for securing 7/8 inch tubing on Bimini tops and canopies. Constructed from 2.304 stainless steel, they offer excellent corrosion resistance in harsh boat environments, preventing rust and maintaining strength over time.
Each pack contains 8 screws, making it convenient for full frame installations or replacements on multiple boats. Their durability and fit make them an ideal choice for sailboats, yachts, and other vessels requiring sturdy mounting hardware for shade and canopy frames.

Buying Guide for Screws and Repair Products for Fiberglass Boats
Corrosion Resistance
Marine hardware must resist saltwater corrosion. Choose screws made from stainless steel grades like 304 or 316 for the best durability in harsh marine environments. Coatings like zinc or galvanized finishes are less ideal due to reduced longevity.
Size and Compatibility
Screws need to match the thickness and threading requirements of boat components such as decks, rigging, or frames. For accessories like Bimini tops, measure tubing diameters carefully (commonly 7/8 inch) to ensure a secure fit with designed screws.
Strength and Holding Power
The chosen screws should offer high tensile strength to withstand vibrations and stress. Structural repair putties and fillers should bond strongly to fiberglass, wood, or metal to restore load-bearing capacity after damage.
Installation Ease
Products that offer straightforward installation, such as pre-thickened putties or screws with compatible threading and heads, reduce project time and errors. Pre-drilled holes or included hardware improve convenience.
Purpose-Specific Features
- For deck or hull repairs, use fiber-reinforced polyester putty for durability and flexibility.
- For mounting or structural fastening, stainless steel screws designed for marine use are essential.
- For anchoring, consider stainless steel sand anchors with grip-enhancing designs for secure mooring.
- Protective accessories like keel guards help prevent physical damage beneath the waterline.
Material Compatibility
Ensure repair products and screws are suitable for fiberglass and other materials present on your boat, including aluminum or wood. Adapting hardware that bonds well with different substrates improves the longevity of repairs and installations.
