FAQs
Can this be used on metal surfaces?
While intended for GRP, it can adhere to metal if the surface is heavily abraded (sanded) to create a mechanical bond.
How long does the repair take to dry?
The resin typically reaches a working cure within 30 to 60 minutes depending on ambient temperature.
Is this kit waterproof?
Yes, once fully cured, the resin provides a completely waterproof seal.
Can I paint over the repair?
Yes, once sanded smooth, the area can be painted with standard automotive or marine paint systems.
Do I need to wear protective gear?
Yes, you should always wear gloves and eye protection when handling polyester resin and glass fibre.
Troubleshooting
Resin is not curing/remaining tacky
The ratio of hardener to resin may be incorrect; ensure you are measuring accurately and mixing thoroughly.
Air bubbles trapped under the glass fibre
Use a metal laminating roller or a brush to dab and push the air out from the center of the patch to the edges.
Difficulty spreading the resin
Work in smaller sections; if the resin begins to thicken (gel) too fast, mix a fresh, smaller batch.

Setup, Compatibility & Care
Preparation is the most critical step when using this kit. Ensure all surfaces are free from grease, oil, and dust, preferably by sanding the area to provide a mechanical key for the resin. Use the included hardener sparingly according to the instructions, as adding too much can cause the mixture to kick off prematurely. Always work in a well-ventilated area and wear protective gloves and eyewear. For long-term care, ensure that the cured repair is primed and painted if exposed to direct UV rays, as this will prevent the fibre glass from degrading over extended periods.
