The topic of sluggish centers, among other things, is interesting as I hear other techs describe their experiences. It's fascinating that at times I wonder if I am in the same business. After 25 years, 8 of which are in moisture land (Florida), I can report that I have NEVER failed to permanently remedy a moisture filled action with my juicing formula of Naptha and mineral oil (8:1). Some cases were more difficult than others, requiring several treatments. However, these tough cases were still handled at the same visit with very little reoccurrence 4 months later. Another quick treatment at the next tuning time always takes care of the problem (permanently). Vertigris, however, is a different story. Naptha and mineral oil will NOT make a dent. Protek claims to be a solution to the vertigris problem but it is not. I have been using protek for verdigris for 3 years now and I can report that it is a TEMPORARY fix at best. Howard S.
