Nothing you paint on the inside will do anything to stop leaks.
Leaks must be stopped from the outside of the bus.
That is not a opinion, it is Fact.
Think about this Austin.. So you have a leak. Water is getting into the walls, floors and roof, rusting out the bus. And you're thinking you want to allow the rotting to continue and build a waterproof bubble inside
Ok.. so you do that. You could build an encapsulated, waterproof capsule inside the bus. What's happening to that leak? It just keeps letting water in and rotting your bus away. Not only that, but this waterproof capsule will probably end up accelerating the rot by keeping the moisture trapped up against the steel.
In a couple years your waterproof capsule is lying out in the open on top of a pile of iron oxide with some wheels and windshield glass lying around.
Ok, that last statement is a slight exaggeration, but why would you put any work into the bus interior if you're just letting the structure rot? Maybe if you were disposing of it next year..
Sealing it from the inside isn't sealing at all. Sealing is done from the outside. Water coming through the roof of your house? You don't "seal" the ceiling drywall with some bedliner, you fix the leak in the roof.
