From East Coast Fibreglass, in this video Martin shows how to prepare, seal/prime, reinforce and fibreglass a wheelhouse using polyester resin, gelcoat and flowcoat/topcoat. This is a good process if you haven't got the budget for expensive epoxies and not too fussy about a moulded finish or if you just prefer and have experience with polyester and chopped strand matting. Please note that this was filmed in a well extracted and ventilated workshop where styrene levels are monitored for safety. we would recommend wearing a dust mask when cutting, sanding etc and wear a vapour mask if ventilation is poor.
