What type of sealant to use on P floor panels?

[SKYMASTER44]

Dear "SkyKing"

If the "Highly" paid materials and process person
say it is not to be used on the aircraft, his expertize is good enough for me (and this Co. and the 45 million dollares aircraft that's is produced here). This Company do not pay these guys to came up with "old wives tales", And we have documentation to back it up.
But again your are the Skyking and it is your airplane, you can use anything you want.
Respectfully Yours
