I know they kinda float for a time (I've been washed down a few river crossings) but they eventually take in water
In deep water mine takes in water via the speaker holes in the footwells, through some holes in the firewall, the split gearstick gaiter and the holes in the floor that need welding up

If I can completely seal up the interior, door seals etc so that no water could get in until it came over the rear side panels (its a soft top) would it float in still water??
Anyone heard of one that did?
