Aha, so you are the same bassboy from the TA days . Whereabouts in the country are you?

It is interesting that you recommend Skinz. I was going to go with the Dodomat Pro barrier MLV in most areas (the flat parts of the floor) using a small amount of SecondSkin Damplifier pro where the metal gets thin and 'rings'. I was then going to put Dodomat's vinyl lining over the humps (i.e the exhaust tunnel).
