Hi all, while I was tiling, I dropped a tile into my nice new white acrylic bath. I had filled it with water to minimise any damage something like that would cause, but it still left a small red dent in the bottom of the bath. The red is from the colour of the ceramic (not the colour of the tile face). Now the dent isn't big, but the colour makes it noticable. I've rubbed away at it and it's not budging just with water/elbow grease. Does anyone know what I can use to remove it? Alternatively, what can I use to touch it up? Would normal acrylic paint do the job? I'm thinking of the touch up job, as using any kind of "agent" to try to clean it could end up discolouring the bath. Advice/ideas appreciated...
