smooth...to be watertight.
Here is a method of making your own:
Get silicone RTV, either the automotive or aquarium/bathtub sort. Clean and
level both surfaces. On the removable piece, lay a coat of thick oil with
your fingertip...this is a release agent. I expect thta wax would work, but
I've never tried.
On the fixed part, lay a 4-5mm bead of the RTV. Now, place BBs or shot, etc.
in the bead about every 15 cm. These will servce as spacers to keep the
movable part from extruding the RTV out the gap. Plade the movable part on
the seal and wait until the RTV is completely cured. Remove the lid, dig out
the spacers and fill in the holes....you can simply smear it in with a
fingertip. When those little bits cure, you have a gasket. I ahve separated
parts gasketed like this many times without harm to the gasket, yet it never
hardens.
Good luck/Carron

smooth...to be watertight.
