Getting the bird ready for spring. Seem to be getting alot of rust on the underside of the frame. Cleaned it up and used Por 15 on the bad rust spots. It just looks so "old" under there. I do like how the Por 15 black looks on the frame. My question is: Should I undercoat the whole frame and under carriage with a product to make it look a bit better and help slow down the rust? I do see undercoating spray products for this purpose. Any ideas or suggestions would be greatly appreciated.I would like to make it look a little nicer under there and help slow rust down a bit. Thanks
