I just got some new MTH coal hoppers and my plan is to realistic up the coal loads. I purchased some black real fine fish tank gravel that looks like coal. My question is. What type of adhesive should I use to adhere the gravel to the plastic load? Anyone got a suggestion? Do they make a spray on? I’m a woodworker and I’ve used that 3M spray to hold sanding discs on a power sander. I wonder if that would work. Help!
