My pool has a set of fibreglass stairs and on one of the steps there is a small chip the size of a dime that has rust or discolouring to it.
I tried the vitamin c pill and rubbing it on it but no luck in getting all of it off.
Is there any white epoxy or silicone I can use to dab onto this spot to cover it? Nobody ever notices it but I do! draws my eyes to it and it must be easy to repair. Now the kicker. Can your recommend a treatment that I can put on this spot while underwater?! It is the very bottom step so not really interested in draining it down that far.
