There has been a lot of talk on the Reno local yahoo groups about neck gaskets gone bad. I hope this helps.

Description: How to replace a neck gasket in your Drytop
NRS makes a fantastic kit for replacing neck gaskets which makes everything very easy.
Here are my household replacements, which you’ll need to replace your neck gasket if you don’t
buy the NRS kit:
Stuff Needed:
- Sharp scissors
- New neck gasket of the same size as your old one
- Small amount of Aquaseal or Seam Grip
- Rubbing Alcohol and cloth or paper towel
- a small piece of cardboard or popsicle stick to spread aquaseal
- either double-sided scotch tape (or painter’s 2 sided tape), or some duct tape
- a heavy object to hold it all together overnight
- 2 dinner plates that are slightly larger in diameter than your neck gasket’s outer rim

Step 1:
Cut your old gasket off your drytop using sharp scissors.
Leave about a 1/2″ rim of the old gasket that connects to the drytop material.

Step 2:
Turn your drytop inside-out and place one of the two plates between the gasket and
outer cuff material.
I often try to raise the plate up on a paint can or something so that the rest of the drytop
hangs lower.
Now use the rolls of duct tape or 2 sided tape to tape the underside of the gasket rim
FLAT to the plate.
This will hold it in place and secure it in a flat position.

Step 3:
Prepare the old rim and the new gasket by sanding and then cleaning with rubbing
alcohol.
Sand the old gasket rim and then rub the rim and drytop material all around the gasket.
Do the same thing with your new gasket’s shiny side. Sand about an inch up from the
bottom and then wipe it clean with rubbing alcohol.

Step 4:
Squeeze a very thin bead of Aquaseal or Seam Grip all around the rim of the old gasket.

Use a small piece of cardboard or popsicle stick to spread it all the way around in a very
thin layer.
You want it to cover the rim, and spread about 1/2′ down onto the drytop material. Make
sure that it’s a thin coat.

*****Aquaseal/Seam Grip warning!*******
This stuff is extremely difficult to get off of you once it’s on your
hands. Soap and water will not take Aquaseal/Seam Grip off of your hands!
Once you feel it’s stickiness on your hands, just rub your hands in dirt or
grit. It will stick to you, but allow you to “roll”/rub it off my hands once it
dries a bit.
Step 5:
Carefully place the new gasket shiny-side-down onto the glued area.
Make sure that it’s fairly well centered and press it into place all around.

Take the 2nd dinner plate and place it on top of the new gasket, which should press
down on the gasket and hold the edges in place.

Put something relatively heavy (10 Lbs or more) on to the plates to press them together
overnight and let it dry for AT LEAST 8 HOURS BEFORE MOVING.

Take it all apart and enjoy your new neck gasket.
Total work time: 20 minutes! Total dry time: 8 hours.
One more thing. . . I apologize for the pictures. These were taken before Stephen and I met. I know, he looks ridiculous.
