I didn?t have this issue with the small engine (O-290) but with the new engine (O-360) and prop I would find aluminum dust on the prop and trailing behind the screws on the forward spinner bulkhead after each flight. (It shows up as smokey colored dust.)
It was bad enough that you could see the weave of the fiberglass in the aluminum bulkhead.
A friend suggested I put a light coating of silicone on the spinner where the bulkhead touches the spinner. I guess you could do the same with fiberglass but I was worried I would never get the spinner off again if I used epoxy.
100 hours later and no more smoking spinner and yes, I can get the spinner off.
