I used fiberglass type window screen rolled up tight. Made like a cigarette
filter and put in every element and boom ends. Had trouble with mud wasps or
similar insect building nests and causing corrosion. They would pack it tight
and elements would fail due to the corrosion of aluminum. QST had an article
about it sometime ago.
