Hi guys, I was wondering if anyone had any recommendations for a good rubberised/waterproof paint.

Basically we've got a water leak in the roof, I thought it was from a couple of small screw holes where a previous owner had fitted a beacon or some such but I've sealed those. I think the water is getting in along the seam that goes width wise across the front and back roof panels that's just behind the front doors. We've repainted the roof with a decent paint but we've still got a leak. Not a massive one but big enough to be annoying.

Was hoping that someone could give a recommendation for something that can be painted on that seals better than normal coach paint. Black for preference.

UK stockists preferred

Cheers
