Snook (Steve Medina) mentioned this product on the Roadfly E46M3 board.
Like he did, I purchased mine from Summit Racing. Nice company to deal with. On your first order you get the product, hat, stickers and a $10 coupon for the next order.
The product is .027 inch thick. Easily cut and the adhesive sticks very well. Based on my experience, I would Sharpie black the edge to hide the fabric before applying.
I purchased this item for several things. One was for the airbox. I spent four hours doing the airbox. Only part that shows is shown in the pics.
