I just bought the rubber gaskets for the hatch and the lazarette. As I was about to remove the old gasket from my laz, I noticed that it is held in place by some sort of gasket cement.
Anybody have suggestions as to what to use to clean up the old cement and what new cement to apply? I have a tube of gasket sealer from the auto parts store. Is that OK?
3M 'Super Weatherstrip Adhesive' , otherwise known as "gorilla snot". Nasty, gooey, yellow stuff...very permanent. Get it at any autobody supply house and many parts stores...accept no substitutes.

Not knowing what the weatherstrip was glued on with, I'd start with what was to hand. Starting with the least lethal:
Naptha (the stuff that removes labels and baked on plexiglass paper.)
Goof Off. If you haven't got it, you can find it in very small containers. It's a little more serious. Then I'd try the
Lacquer thinner. If the stuff hasn't desolved yet, try some
Paint remover. Try to find a brand that doesn't have methyl cloride in it. Probably the easiest way is to head over to PepBoys for some
Gasket Remover. Usually an aerosol composed of a cocktail of solvents like xylene, acetone, toluene & MEK. Loctite, Permatex, etc. Havn't used this stuff myself, just a suggestion. Breathe this material, it'll take a few years off your life too, along with the gunk. A universal solvent for a mere 7 bucks. You try it, OK? Tell us if it works!
Believe I used a newly sharpened scrapper.

My lazarette hatch gasket is in need of replacement. Is there a source for these?
Thanks,
Marcelo
Here is a previous response (See Below). You can read a few more details on (inadequate) replacement options considered on this thread:

on posts #52 to 56. Below is the basic story.

Weatherstripping
A number of years ago, the association had the Pearson weatherstripping reproduced for the lazerette and forward Ariel hatches. It is now sold out, but if there is interest, we can order it again. The minimum production run equals 50 or 60 sets. With the recent price for poly anything going through the roof (and postage rate increases), however, the price is unlikely to be as cheap as it was before. Here's the write up from the old order form:
"The Association has reproduced the weatherstripping used by Pearson on Ariel yachts. It is being made available in kits containing ten feet of a larger extrusion for the lazarette hatch and six feet of a smaller extrusion for the forward cabin hatch. Each extrusion is cut longer than necessary to allow for possible variation in hatch rim circumference. Shipping is via Priority Mail. (Note: forward hatch on the Commander is 6'-6" in circumference. We will be cutting this length.)
Weatherstripping Kit (2 lengths) $ 48.00
Packaging and Shipping 7.00
Total Per Kit: $ 55.00
The original spec gasket is wonderful stuff. I have it on the mephisto Cat. There are at least a handful of interested buyers out there... I would be interested in a couple of sets myself...
First: the original gasket shape and material s to be preferred.
I still have A338's fore hatch which is a tight fitting lid on its coaming.
When I got the boat the hatch coaming had no gasket - but this would be a good place for one.
The gasket-seal slips over the edge of the upright coaming and makes a contact seal on the inside of the top of the lid. The rubber gasket can be a compressible hollow bulb, foam, or ribbed.
The lazarette lid on A338 seemed to be sprung. It did not rest snug on the deck.
A gasket on that coaming would have to be adjustable to the variable space between the coaming and the lid. I believe the original gasket could be adjusted.
If there isn't enough interest for a quantity order on Bill's part, it may be possible to find something in the McMasterCarr catalog.
EG on pg 3438 there are some edge grip seals in various styles,
but none like the original Pearson.
If I remember the lazarette coaming edge was about 1/4". There is a 1/4" grip EPDM/vcinyl bulb version that might work there.
ADHESIVE
EPDM is the usual weather resistant rubber used for windscreens and doors in the automotive industry.
Rubber adhesives are contact cements where you coat both surfaces, let them dry, then press the gasket in place. Some cements don't aggressively grab and allow for very careful positioning.
3M has a weatherstrip adhesive specific to EPDM called 08011 BLACK. It is a contact adhesive, not a bonding glue.
Using an adhesive on the coaming edge where the gasket has to be saddled in place would be chancey to say the least. I'd coat the gasket groove and slip it WET on the uncoated coaming.
After the nasty solvents dissipate, seems to me there would be an adequate grab.
imco, not recommending this, haven't done it, but have used the adhesive.
HH-66 vinyl/pvc contact cement (not pipe cement) can also be used WET if you are sticking vinyl to the hatch coaming. Versatile and weatherproof.

I also would be interested in at least one set possibly two.

A man can succeed at almost anything for which he has unlimited enthusiam.
I could use a set for the lazarette and forward hatch on Sirocco but I also need some of it for the cockpit seats. I presume the weather stripping if the same for all. If I'm wrong about that someone please let me know. thanks,
I am definitely interested in a set for both the lazarette and forward hatch.
I have no gasket on my lazarette. What's the function?

Jon,
As I understand, there is no need for seals / gaskets on the lids on the cockpit lockers. The drains are nicely designed to keep the water out.
It is hard to get water in there... Even while pointing a hose at them...
It is important to keep these from opening while in heavy seas in case you're pooped/rolled... Not often an issue, hopefully!
Kyle,
The Lazarette gasket is important to keep that compartment dry. (Think inboard motor).
I have the gasket on the Mephisto Cat's laz, but it just provides a nice cushion for the lid...
Since I have an outboard in the lazarette, there is often quite a bit of water there...

I would definitely be interested in two sets of these.
Otherwise I will be fashioning something myself...

Does anyone have an updated source to obtain gaskets fro the foward hatch and Lazzaret? If not can you please post a picutre ofthe gasket and I will try to find the most similar one in McMaster Carr.
Thanks

For the actual material dimentions and comments on McMaster carr alternatives at the time.
Thanks Rico.
I think I wll be stuck with th McMaster Carr weather stripping unless I can find something better
