I use CRC on a rag once a week to wax the blades (R22) and find that nothing sticks to them, It also makes life very easy when it comes to cleaning the blades and I have also found that erosion levels are dramatically reduced too. On comparing 2 sets of blades with 1200 hours on each having operated in the same environment, It was really noticable how the CRC'd blades had held up.
For the R44 we use a rag taped to a broom and run it along the leading edges with similar results.
