Anodizing does not conduct electricity, therefore parts of flashlights that must conduct from one piece to another will intentionally lack anodizing on threads or on the end of a tube in order to get metal-to-metal contact. | Anodizing does not conduct electricity, therefore parts of flashlights that must conduct from one piece to another will intentionally lack anodizing on threads or on the end of a tube in order to get metal-to-metal contact. | ||
Anodizing can be removed with strong alkali. People have had luck using a product called Greased Lightning, a degreaser widely available in the US. Then they polish it on a buffing wheel with a metal polish called Rouge. The result is glossy shiny aluminum. Either clear coat or a product called Sharkhide can be used to keep the shine from becoming dull. Here are some examples: [http://budgetlightforum.com/node/7357 DRY], [http://budgetlightforum.com/node/7734 Ultrafire UF-980L], and [http://budgetlightforum.com/node/7737 Solarforce L2i]. | |||
