I have chosen to renovate my bathroom melamine cabinet (as I am not in a position to replace it and it is structurally sound)
Sink and cupboard side
Drawer side
however the closer one looks one can see what a shoddy job they did when installing it! They have obviously just hacked away at it when fitting the sink pipe. It's an area that you don't really see (as one side is hidden by the drawers) but I would like to at least tidy it up so its not so unsightly. I wondered if there was a 'putty' of some kind that I could shape to fit the space to at least close the gap. Then I could sand it back and paint it when I paint the rest of the cupboard (painting the inside as well as outside). Or some kind of melamine sheet or patch that I could glue on? Any suggestions would be appreciated.
