Glass fibre strands 6 mm long that can be mixed to resin to make a dough like mixture and is a very strong compound, make sure the catalyst is mixed well into mixture and do not apply to thick as exotherm will generate making the mix reach high temperatures.
Very useful for reinforcing difficult and awkward areas in mould making and part production, the glass fibres can be sprinkled into awkward areas where matting would spring away, sprinkle the strands into area, wet with Polyester resin then lay matt over, this prevents any air voids becoming present in moulding.
