A cautionary note here.
This "low adhesion" sealant appears to be the same that is used on Grumman AA series planes to seal the access panels in the bottom of the tank (bottom skin). They require it because the panels are .032 material in mid-span of the thin skin, and are basically unsupported. The regular sealant makes removing the panels a near impossible task without bending something. With the "low adhesion" sealant, it is possible. (The warm, sharp putty knife trick.)
However, it is common knowledge about Grummans that these panels will leak, the only question is when. Leaking and oozing bottom cover plates are extremely common in the Grumman fleet. The only saving grace is that these panels are at least out where they can worked on fairly easily.
I would not use it on an RV wing tank, knowing it will only be a matter of time before it begins to leak. I just finished closing up my first tank, and I will use regular Proseal for the cover.
Your mileage may vary.
