Protective coating on polished aluminum

I have several small (3x6x1/4) aluminum parts for my Harley that I am polishing in my garage. I've got the polishing down to a mirror finish, but now am looking to try to protect the finish so I don't have to keep polishing. The last time I polished it, the shine lasted about 3 months and then got hazy, and took me about 90 minutes to get it shiny again. I tried the Diamond Clear from Eastwood =>

Lots of cool stuff there for powdercoating and polishing but my first attempt looks less than promising. Most of the piece came out with a "crackle" look to it and the part that isn't looks hazy. I think the "crackle" finish was due to an error in application, but the haze isn't what I want. I plan to strip it back down and try again with the same stuff, but I anticipate it will come out hazy.

Is there any better way to get a brilliant, protective finish on small parts THAT I CAN DO IN MY GARAGE? I've looked at the decorative anodizing kits, but am a little concerned about the safety. I read other posts in this forum which seemed to indicate some of the fumes from chrome plating are carcinogenic, but yet I see a guy standing over a chrome bath with no respiratory protection. So, not sure if a spray on clearcoat is the answer, or maybe one of Eastwood's home powdercoating kits or the home anodizing kits. I don't plan on doing any large scale work and would like to try to keep this inexpensive, otherwise I may as well try to find a shop to do this work.

Any advice would be appreciated.
