This is a high-viscosity polyester laminating resin. It is "clear" in the sense that it isn't opaque like body filler, but it typically has a slight honey-like amber tint in the tin, which clears up significantly in thin layers.
Key Features:
- Structural Integrity: Designed to soak into (wet out) glass fibre matting to create GRP (Glass Reinforced Plastic).
- Substrate Compatibility: Bonds exceptionally well to metal (steel/aluminium), wood, GRP, and masonry.
- Weatherproof: Once cured, it is completely waterproof and resistant to oil and acids, making it a go-to for boat repairs, rusted car floor pans, or even garden ponds.
- Rapid Cure: It is formulated for a fast "gel time," allowing you to work quickly on vertical surfaces without excessive sagging.
