You mix the resin with a small amount of hardener and the apply to the surface you want to over with fibreglass matting

Would this repair a shower tray?

That's what I used it for. Mine was cracked around the plug hole and it sealed it and is probably stronger than before. Only downside is that it is not white when dry so I had to paint over it afterwards. There are more expensive versions that are coloured, so you might be better with those.

Have quite a long deep crack in the bottom of my bath will this work ?

my experience of this is that the resulting mend is quite lumpy and rough textured. I think it would stop the leak but be uncomfortable, difficult to get smooth enough. NB This is only a guess as to the mend and the finish.

is this product suitable for underwater use on a boat?

Possibly. Apply plenty* of the product in a warm dry area. Good luck. * several coats.
