Hi Sangeff, I've recently noticed that afew cracks are appearing in my plastic rotor on the exterior--don't kow if it's the retrofitted neo's that are doing it or caused it --or it's breaking down under the uv.

I will be painting mine soon and now have a question --what is the best type of paint to use-I think electricians paint that orange pvc electrical conduit (above ground) with a paint ----at least that's what the code requires them to do (seldom see them do it )

The drum thing seems a good idea if you can manage to fix it very securely so that it dosen't vibrate and rattle.

cheers

Bruce
