I'm thinking the best way to stop roof leaks once and for all is with spray on bed liner on the roof. Can anyone recommend a good brand name that might have a dealer in the Minneapolis area?
We had the bed of our Ranger sprayed at a place in Rogers. I think it's called ArmaCoatings. They did a great job. 2 hours. $428.
It's a little harder than Rhino. Not quite as sticky, but seems to be holding up very well though we don't haul much more than groceries in it.
They had a display of several different colors they can spray. No idea if they can do a bus roof, but I suspect they could. They have a pretty big
shop where they do the spraying.
