I have a mahogany porch railing, going into its third summer. For the past two years I have applied a brand of "Australian" oil, which does not seem to maintain very well. I did some web searching, and found recommendations for tung oil (50/50 with mineral spirits). Consumer Reports recommends a Thompson semi-transparent product, although I like the wood color and grain to show through. I live near Boston, so lots of air pollution (dirt) and full sun (lost a 75 year old maple last summer).

I'm looking for durability, ease of application, and less noxious fumes (who wouldn't?). Please respond with specific brands.

Many thanks,

Lynne
