I have a thin plastic livewell which has been leaking recently. There are 2-3 spots where it has been patched before by a previous owner which either have just wore out or were probably not done right. Whatever was used to patch it dried hard as a rock and seeing how thin my livewell is, it bends slightly at the bottom with the weight of the water and probably worked them free. I'm planning on trying to remove the old patch material and re-patch. I'd like to use something that dries soft like silicone. I'm sure there are a number of things that will work just fine but just wanted to check here to see if anyone had any advice on what to use. TIA.
