I need to repair a badly damaged gravestone. It appears to have been hit by a mower and a large chunk of the base stone broken off. Parts are missing. I think the best way to repair it is with Isopon, which will stick the existing bits back and fill in where missing. However, I want the colour to match the original stone, which is a greenish colour.
Does anyone have a better idea, and/or know of a way of colouring Isopon so that I can match the stone?
