Purchased your DryerJack. Do you suggest it be painted or left bare? If painted, what type of paint? Thank you.

Carl, thanks for the question.  Painting aluminum is considered a special application and requires some prep work.  Here are the highlights from an eHow article. 

Aluminum surfaces need special preparation before painting. This differs from most surfaces in that aluminum must be etched. Etching is a technique that involves coating the metal with an acid, which causes a chemical reaction that in turn produces a slight engraving. This helps paint adhere to the aluminum surface. Vinegar, a weak acid, can be used to etch aluminum in preparation for painting.

1.   Mix together a solution of equal parts water and vinegar.Coat the aluminum in the vinegar mixture and monitor it regularly, applying more vinegar solution if it begins to dry. Allow the vinegar solution to work until the aluminum surface becomes dull and darker.
2.   Wipe down the etched aluminum with warm, soapy water. Rinse it thoroughly with clean water and pat it dry with a lint-free towel. Allow the aluminum to air-dry.
3.   Apply one or two coats of aluminum primer to the etched surface with a paintbrush or small paint roller, following the manufacturer’s directions. A paint roller will ensure a smoother, more even coat. If you are using a paintbrush, use long, even strokes. Allow the primer to dry.
4.   Paint the primed surface with 100 percent acrylic latex outdoor paint with the highest volume of acrylic resin as possible. Use a paintbrush or paint roller, apply one or two coats as needed, then allow the paint to dry according to the manufacturer’s directions.

Here is an FAQ from Rustoleum regarding the painting of galvanized metal. 
Q Can aerosol paints be applied to galvanized metal?
A Yes, if Aluminum Primer is used as a base coat and allowed to dry for 24 hours before applying aerosols. Most all of our spray paints are oil-based enamels. If applied directly to galvanized metal without the primer, the oil in the paint will react porrly with the galvanized.

Hope this helps.  Lots of similar articles online.  Your paint technician at Depot or Lowes should be able to help too.  Good luck.
