Currently in the doghouse for drying two cars' worth of mats and sound proofing in the living room. Apparently the bathroom would have been more acceptable, but the radiator is a lot smaller.
They can hold a lot - but its only a few hours drying time on some warm chippings in 30-40 degree heat in rural France.
Thats how I dry mine - once a year, I strip it when we are over in the hovel and lay it all out on the chippings. SWMBO and my mother go spare as 'the place looks like some bloody Land Rover scrapyard!'
