I used this product to repair a chipped enamel bath. I do not expect the repair to last as long as having the bath re-enamelled but so far it is staying put. The product is very white, whiter than the enamel but not appreciably so and much better than the black patches it has concealed. I also used it to repair a chipped WC pan where the repair is more visible being whiter than the porcelain. The product is easy to use and the ability to smooth out the material using water enables a smooth transition to the surrounding material. I would recommend this Superfine Epoxy Putty as a useful repair material for a variety of uses.
