I've used CLP since 1984 and have never had anything like what was described happen. At work, we took 3 of our old tools which were being replaced and did an experiment. All of the tools in the test were exactly the same. One was coated with WD-40, one with CLP and the third nothing. The tools were set aside in the same area on the apparatus floor so that their exposure would be the same. After 3 months the tools were compared. The tool with nothing had some light surface rust on some areas. The tool with CLP looked just as it did on day 1. The tool with WD-40 had a white, powdery corrosion over its entire surface.
The purpose of the test was to determine what, if anything, we could put on our tools on the fire trucks to keep them from rusting if they were to go for a while without being used. From that point forward, we have given our metal tools a light coat of CLP after they have been used and cleaned.
I dream of a better world. One where chickens may cross the road without their motives being questioned.
