Hi Lynn, I think that Glisten would be worth a try - the POR guys have a metal prep solution called AP120 specially designed for alloys. I have used this on highly polished alloy (just brush it on, leave it for 2 mins & then hose off). It doesn't dull the surface like many other metal prep products. The Glisten itself if truely self-leveling - after trying a few bits with a brush application, I have stayed with it ever since. Two light/medium thickness coats seem to fill all scratches & the final finish is dead smooth. Whats more, the pot life of the stuff is amazing for a 2-pack product - up to 3 days in a sealed jar (and yet, when painted on, it is touch-dry in an hour or so !).
