i want to make a cave and stick it with silicone i was going to by some aqua silicone. My father told me then the normal silicone would be ok as long as i soak the parts i used silicone in water for a day or 2! He said to use the normal one because aqua silicone here in ireland costs €11.00 and normal silicone costs €3! so is that ok to use normal silicone?? 8)
