Ok, I'm gonna take
@Alan 's Idea a couple of steps further and modify the blanket to repel moisture as well as dirt, heat and noise. By cutting both the dampening material to fit as well as the Reflectix/reflecting bubble wrap. both will be identical in length and width plus both will have matching holes for where the roll cage, seat belts and seat attaches. I'll tape all the edges around the circumference as well as tape all the edges within all the matching holes. In theory, this should give it the full spectrum of protection. So, which side should face down, the reflectix, or the gray poly backing of the blanket material?
I wish the blanket material was thicker but this is what I already had on hand. The Aluminum backed Gutter Flashing will be my tape.
PS I made sure to include some feet pictures for all of you foot fetish freaks out there...You know who you are....
