How best tio repair a small puncture hole in the bottom of my bath?

Well I fixed it without advice, and it seems to have worked out fine:
I first used my coloured sealant from above, smoothing it flush with an old credit card (and having an adhesive patch in place underneath, to stop the sealant going through). Then when that was set, I applied 'No Nonesense' External Sealant on a patch of very loose woven cloth thickly from below (I bought this from 'Screwfix). Even I have trouble finding the mend now :-)
