Over the winter, I'm considering fitting Dynamat to the panels of my Plus 4 to try to reduce the road and engine noise. I'm curious to learn how effective it is likely to be, how much is required for one car and whether its best to buy sheets or rolls? It's not cheap so I'm trying not do do my usual trick of buying far too much and then watching the excess slowly deteriorate over the years!
