I was given some great advice that I have tried for stock blade treatment and like it very well - strip all of the plastic covering off and coat them with Epoxy. I used the standard 2 part that comes in the dual syrynge looking thing from Home Depot. It was difficult to get a real even smooth coating, but some sanding after helped a lot. After sanding I spray paited and balanced them and it spins up to a hover with Zero vibration or wobble and hovers as well as my perfect condition carbon blades!
