l was taking some board off the side of the bath to replace it and did not pay attention to the top of the board being under a lip at the top of the bath when l pulled it out and broke 2 small pieces of the side of the bath.It looks to me like a fibre glass bath so will it be a acrlic coating for this type of bath.The reason l ask this is because will l be able to repair this, l have looked in the screw fix book and they have a enamel-ceramic scratch and chip repair kit. As anyone used this product before. Is it any good or does anyone know of any other repair methods to make it look ok
