All of our bodies are carefully hand laid with the finest of materials. High temperature Vinyl Ester resin is used in all panels with a quad directional sewn cloth – not chopped strand matt. (CSM)

This is an aerospace material as opposed to the "normal" fibreglass or GRP materials of polyester resin and CSM. The heat deflection temperature of our resin is 105 deg C ( polyester resin is 74 deg C ) When you consider that the engine compartment temperature can reach 80C plus, it becomes clear why we use this resin. The strength of the resin is also much higher; Vinyl ester resin: tensile strength 95 Mpa Polyester resin: tensile strength 62 Mpa Fibreglass also has to be post heat cured @ 80 deg C for 4 hours to reach this strength and to reach it’s heat deflection temperature. We have combined this high strength resin with the exceptionally strong sewn cloth in a composite structure that produces an extremely light but very, very strong structure.

Due to it’s much higher strength, it’s thickness can be reduced thereby producing a structure that is less than half the weight of a fibreglass product yet is 32 times stronger! This is achieved by the use of the sandwich concept, the flexural rigidity and flexural strength are substantially increased in comparison with a solid laminate – if you double the distance between the laminates, you increase it’s flexural strength by 12 times. With this result, you may wonder why others don’t use these materials, simple – cost. The resin is twice as expensive and the cloth is 8 times more expensive! Makes you wonder why their prices are similar to ours. Why settle for less – this is the 21st century!
