Reel, I have a friend that did his alum trailer that way about 6 years ago and the poly is still looking good. But there does seem to be a slight yellowing to it after all these years... (The poly, not the alum itself.)

NJ was originally made for the US Navy, and was made to remove rust from steel. Then several years after the original they came out with NJ for aluminum. One bottle is a pink label, the other is a blue label. I forget which is which.
