deck sealants

[learning to fly]

, i am looking to seal the access panel on my hurricane 630. It is almost the whole floor behind the console. gives me access to the gas tank and all wireling. im wondering what i should use to seal and it up so that i can have access again if needed without a whole lot of hard work . i dont want to use only silicone since i would like to have some fastening ability with the sealent. sech as 3m 4200. i know the 5200 is almost permenant. my question is will i have a lot of trouble breaking the bond of the 4200 if needed. is there something else that may not be as strong i could use, thanks for any info

Sikaflex 221 works well as an adhesive sealant .

How about something like this if it has to be removable......

would the silkaflex 221 be easier to pry apart than the 4200 if i ever have to open up the deck again. Its about a 3' by 4' slab of decking. its fastened by a bunch of screws for strength and was sealed with something that had great holding power but i was able to remove it without too much hassle. im hoping its years before i have to open it up again , thanks for any help

Yes easier to pry apart than 5200 and cures faster
