To protect aluminum, try Alodine, a surface treatment that provides a layer of corrosion resistance. You just paint it on. Paint will bond to it.
If you're willing to do a little chemistry and have a 12 volt battery charger, try anodizing your aluminum parts. The advantage of this process is it's cheap - only thing you buy is battery acid and some aluminum wire. You can also dye your finished parts any color you like. Down side is that working with acid is troublesome and messy.

Powder coat can be cheap if done yourself. Here is my system: http://www.kr2seafury.com/2.html www.harborfreight.com/ has all you need but the oven OR I use the Craftsman gun...Ebay Item number:320695170539 Some folks believe it covers to good and flaws in welds will not appear if powder coated but I think the hard shell finish will crack if your welds crack so I powder coated my gear.
