Spoke to Darren, who was, as usual, incredibly helpful and he arranged for me to be sent resin, top coat, catalyst and some bandage to repair a new crack in our internal gutter. Unfortunately, when the box arrived it contained no resin. I contacted CRS, and sent some photos of the box and its contents, as I thought I needed to convince CRS they had not sent the resin - there was only the indentation of the top coat tin inside the box. Darren arranged for the resin and its catalyst to be sent, and it arrived a couple of days later. The quality of the materials was absolutely first class, and the bandage awesome - much better than what I had previously sourced from elsewhere. I will continue to recommend CRS to others contemplating GRP work. I am hoping to fibreglass my garage roof next year, so will be back for more materials before too long. Many thanks - especially to Darren!
