Hi all,

I should be picking up my TCH in the next few days and wanted to get a general concensus on undercoating a TCH. I notice that the rear wheel wells have a shag like material on them and was not sure what or why it was. I'm guessing that this is some sort of sound insulatation so I suppose it should not be undercoated over. Also, what does undercoating do to the drag coefficient of the under carriage?

Thanks
