A few months ago I cleaned out my windscreen washer reservoir/washers and doing so I knocked a rubber gromet out of a hole in the bottom (it was disintegrating). As I can't get to it I just pushed a bolt in and then poured some superglue around it and left it a day. Then did it again and filled it up and it held but now appears to be leaking very slightly.

Anyone got any ideas how to stop this leaking, it's getting low so before filling it up I'll let the area dry and then is there any product which will "seal" the whole area from the outside. Epoxy Resin? I have some 10yr guaranteed exterior water proof paint, would that do it?

Silicone sealer?

About as good as you will get, or see if there is one at a breakers.

I did try and mend one of those hand pump pressure sprayer that had a small impact crack.
More the challenge than being practical. Nothing I used worked ... the pressure flexing it cracked everything I tried.
At least this is not under pressure but will be subject to flexing ... weight of water and the motion of the car. :(:(
EBay might be your friend.

Super glue is water soluble!

Either fibre glass matting and resin or, try

Thanks for the responses, I never knew superglue was water soluble, it's done well to hold for a few months then! I've found some spare silicone kitchen and bathroom sealant. It's clear, not white so no real use on kitchens and bathrooms so will try and empty that all around where the leak is and see if it stops it

It’s not water soluble, it’s a cyanoacrylate adhesive which uses condensed water between surfaces to create the ‘hardening’ reaction. This is why you need 2 x surfaces when using this as a glue, it’s not ideal as a filler, but might work as it has done in your case.
Epoxy resin with some glass cloth is the only real permanent fix, but that involves removing the resevoir and at that stage it might just be best replacing it?
Edit: there is this stuff on ebay

Superglue is an amazing hard filler when used with fine powder in small gaps.

I wouldnt use epoxy resin.. to hard and will never stay stuck to plastic, especially when it expands and contracts.
Sika does a brilliant hybrid sealant, £3 from toolstation and supposedly can be used to bond even under water.
