Fuel tank access panel (making weather tight)

[colinm]

Hi
Thanks guys.
I don't use any silicone products on the boat.
How about "Boat Life" or Sikaflex....both above the waterline products....
I was going to install a few screws to hold the panel in place and seal. i didn't know if there was a certain product spec'd on the market? No need to get below deck i that area, only if the tank needed to be replaced.
Thanks again
