Ron- we appear to have a misunderstanding about Tar and Bitumen. My
dictionary says " Bitumen: Any of various mixtures of hydrocarbons and
other substances, occuring naturally or obtained by distillation from coal
or petroleum, found in asphalt and tar, and used for surfacing roads and
waterproofing."
In other words- just different consitances of the same thing.
Bill's experience is with applications where salt can get to buildings. I
agree with your assesment about getting to towers, but the natural exposure
I see (acid soil) is just as bad. Where you live, in Florida, salt from the
ocean gets many miles inland.
