Well, couldn't it just be that you have not experienced every possible
environment where galvanic action might take place? The term "advertising
puffery" offends me and suggests that I am not telling the truth in my ads. I
am about to take down one of my towers where there is a Telrex aluminum boom to
mast plate at the 125 foot level with severe pitting of the aluminum where it
has been in contact with stainless steel bolts. When I get it down, I will
photograh it and put it on my web page for all to see . . .
