[TowerTalk] Any harm in pressure washing a tower ?

[Pete Smith N4ZR]

My Rohn tower used to be part of a broadcast station - when I got it, it 
was covered with wide stripes of orange and white paint.  I rented a big 
pressure washer to get the paint off, which it mostly did, and there was 
no evidence that the underlying galvanized surface was damaged.  I then 
painted it with special primer for galvanized metal and followed with 
ordinary latex house paint, and the finish still looks great 18 years later.
