Tony,I think you will be very pleased with linex,it's indistructable.I think you will not hear any road noise with the windows up.I would'nt cover any nuts and bolts with it,you'll never get the loose in the future.
3m makes a rubberized coating called body shutz. I used it in my 1951 chevy truck.It's black,but i painted mine my body color of the truck.They sell a gun that screws ontop of the can,i highly reccomend using this product.The spray gun will also fit onto the 3m undercoat cans.See the link !!
