For those of you that have use brute trash cans did regular bulkheads seal properly in them since they are circular or did u have to use flex bulkheads?
You can use either or but I would do bulk heads so I can allow silicone allow it for a 100 percent seal. Don't want any leaks ever on these guys.
Silicone does adhere to plastic. Follow the link below. My bulkhead has never leaked. I apply the gasket as normal but for added assurance I apply silicone around it for good measure.silicone does not adhere 2 plastic and can actually make ur bulkheads leak... the rubber gasket makes all the seal u need.
