What type of sealant to use on P floor panels?

[SkyKing]

As to the story about the smell of 'vinegar', it's just that: A STORY!

Any good grade of clear RTV will work well and you'll find this is what most shops use. The chemicals in the RTV aren't going to etch the aluminum. Any unpleasant odor disappears after it dries and it's fairly easy to remove.

Pro-seal is not a good choice for the inspection plates over the gear as you will have a tough time getting the plates separated from the rest of the plane, and it's rather expensive and difficult to work with as compared to RTV. Pro-seal is much better suited for more permanent things.
