They'll be no effect one way or other.
Starting with my CP-helis I have done this to ease the removal of bug guts (aerosol liquid, not RTV types).
Spray on rag, wipe down leading edges. Makes clean-up nearly effortless.
Maybe he did???I thought the OP meant something more like silicone sealant to act as a damper. DUH on my part there.
Yes silicone spray will not affect it at all but be careful.. some lubricants can break down plastics....
