Some people are recommending using ACF50 and applying with a small syringe as it has very good anti-corrosion properties and repels water. So if you get any rubbing due to flexing between wings, body and beading exposing aluminium it may stop any corrosion developing. I have used ACF50 on a friends recommendation and others on TM. (By the way apparently WD40 absorbs water even though it initially repels it)
