Before all of you go to Walmart and spend your hard earned dollars on coffee filters, be aware that I sent Bill Welch a sample of 400 mesh stainless steel that I prefer for window screening in HO scale. We are all awaiting Bill�s learned evaluation relative to it�s suitability for the SAL car.
 
My coffee filter is crude by comparison, so I highly recommend that you wait for Bill�s evaluation. I have a lifetime supply of the 400 mesh, and I�m willing to sell it at cost plus a first class stamp. My cost at the time of purchase was 15� per square inch. I don�t yet know how many square inches it takes for the SAL car, but your total cost is certain to be under $2.00 and probably $1.00 including postage.
