I don't know which Paul you have been speaking to, however, it wasn't me. I abandoned this project when another Website Member said that he was going to have the rubber produced. I was quoted the price for 3000 feet, and the die cost amortized into the total cost, the delivered price was in the $1.25 per foot range. It was going to sell to the end user (PCS Member) for $2.00 per foot delivered, with the small profit going to support the website.
I have used this companies rubber weatherstripping on one of my other cars, and the fit and finish is as good or better than the original that was delivered with the car when new. The company that I was put in contact with, isn't Steele Rubber or Metro Rubber, but a manufacturer of product for the American automobile manufacturers. It was going to be produced as a "prototype" item, since they normally manufacture in 10's of thousands of feet.
As a side note, I know first hand that the rubber that was produced will not work on a 1971 - 1976 Superior coach, since it was tried by a website member, and didn't work. The material was too dense for the door to close and latch.
