Hi there, is this product suitable to repair or fill small digs of the topcoat (gelcoat and poolcoat) at the bottom of a polyester resin pool ? Cheers

This will hold and seal submerged but it is a soft repair for hidden areas like inside light fixtures to seal cables etc. On a traffic area, I don't think this is the best solution.

I have a patch of fiberglass missing on my pool can I use this as a patch?

This holds very well submerged but I'm not sure it is the right solution for a patch depending on size.

We need to fill the gap above the tile and below the coping. Will this work ? And can you purchase additional tubes without purchasing the entire set

Yes. It will work very well. I have use it on my pool several times to fill up gaps between tiles or replace loos ones. You can also buy just the epoxi but they son sell the tips separately. My advice is to use it to join or fill small gaps other wise will be too expensive.

Can you use it in a pond with fish in it

I'm not sure about the toxicity but underwater applications involve placing the adhesive on a piece of plastic slightly larger than the repair area. This is done outside of the water which makes this even easier The KIT includes plenty of the plastic. I think if you leave a 1/2 of the plastic repair patch without adhesive on the edge and press it over the damaged area it will work without contaminating your pond. The plastic can even be removed after about 24-48 hours. One thing to remember is that you want a thin even coat on the plastic. Less is more with this product. Good luck
