One of the projects I've been wanting to do is to change the ugly yellowish foam backed plastic liner on the inside walls of the vberth,the aft cabin walls and main salon walls.one question is do I install a product over the existing stuff or do I remove it and reinstall a similar product.Is there a foam backed product out there and whats it called? One thought was to remove it all and install indoor/outdoor carpet or a Nautilex product(did this on a Chris Craft restoration in the vberth and it looked decent)
