RE: Alpha 40
There is a reason virtually all trainers use banded wings. If you are going to use the airplane as a trainer, leave the bands be. Much further down the line if you still want a bolted wing then go for it.
Also the Rubber is nowhere near the quality it use to be only a few years ago and I do not recomend reuse. Rather just replace them each use. They are cheap. Yes keeping oil off them and cleaning seems like a good idea but it will do nothing for what really kills them, and that is UV from the sun. That is the real killer and #64's can be killed in a single days exposure. The damage is cumlutive from the sun therefore Its difficult to judge suitabilty for reuse other than the cracking from the edge when streached.
If the airplane is to be exposed for a long hot day assembled a simple expediant of throwing a rag over the bands can minimise the uv exposure.
Do yourself a favor, do not convert to a bolted wing for now and do use the bands just once.
