Well, the Daytona 500 is over and I spent all of ten minutes in the shop on the AN fittings........I can only say one thing,,,,,IT WORKS,REALLLL EASY..... Took two sprays with some very old weak oven cleaner and then I passed each part on my grinder/wire wheel brush,gives a slightly rough finish,will polish to a finer finish later,but the wire wheel gets everything out of the little cracks........
Very please with the outcome and took about ten minutes to do.........
