Looking for aluminum sealer??

Anybody have any experience with something to seal aluminum & keep the shine longer after I have polished it. I want to keep my Featherlite trailer shiny but it dulls back too quick after Flitz or Mothers polish.
Thanks Bill

 

google
SHINESEAL
and
Zoop Seal

 

I was wondering about the same thing. I saw a product featured on one of the TV car programs called "Shark Hide" that was supposed to protect aluminum. Haven't found anyone that has actually used it.

 

Shark hide works, but is not esthetically pleasing. I polish for a living(from motorcycles to WW2 Planes) and Optimum Metal Polish is by far the best. Not only does it polish well, but also gives lasting protection.

 

Thank You all for the information
