This is aimed at the use of WD-40 on Robinson helicopters as well as the maintenance of the helicopters painted surfaces.
Robinson does not approve WD-40 however Corrosion X aircraft grade is approved for corrosion protection. It is available in spray cans and in bulk. You can purchase an application kit and several gallons of Corrosion X for several hundred dollars.
The US Army used corrosion X in a test. Two companies of UH-60s were sent to Somalia. One group of UH-60s was aggressively treated with Corrosion X and the other group had no protection. When the two groups of helicopters were returned they were put into refurbishment. The maintenance cost on the treated helicopters was $192,000 less than the untreated ships.
Robinson also approved another Corrosion X product. The name of the product is REJEX which is used to protect the painted surfaces that get contaminated by engine exhaust and bugs.
