Self adhesive recommend for forward hatch gasket

centerline · Mar 20, 2015

im assuming you mean the seal between the deck and the hatch frame, so use sealant... without a gasket.
I like the 3M products, and specifically the 4000UV formula. it is adhesive but still removable if you should ever have the need, and its UV stable... it will probably last a lifetime for the job.

for almost ALL deck hardware, the proper sealant used by itself on clean surfaces will outlast any gasket you could put in there. the gasket material is prone to drying, cracking and then leaking.... as you are experiancing.

dont use sealer... a hatch gasket is proper. if you can find out the manufacture of the hatch, you may be able to get a seal for it... otherwise you may be able to find what you need in this link for self adhesive bulb seal.

Thanks centerline. I picked up some weather trim from pep boys that I going to try.

just make sure the mounting surface is clean clean... new adhesives dont stick well to old adhesives... sometimes not at all.

Looks like you are finding a solution.

I posted on this couple of years ago with my inexpensive DIY experience. Might give you an idea or two:

Starrfish,

I still have the original gasket for my 1980 C30 forward hatch. It has never had an adhesive & has always stayed in place.

One should think before applying adhesive depending on the item. I would first check for the proper gasket for your boat before thinking adhesive. If you have the correct gasket & it is captured in a track, properly install it, keep it rejuvenated & clean and, maybe you will get the same lifespan as my gasket is still running strong with no leakage.

I also NEVER crank down too tight on my gasket, just enough to make a seal.

Just a suggestion,

CR

I agree... its nice to have the proper gasket for the slot that it fits in. sometimes its tough to find that perfect match... and yea, dont over stress the seal until you need to when you have green water coming over the bow.

an adhesive seal is NOT the same as a seal that was installed with sealer, or caulking.... its much easier and cleaner to work with self adhesive weatherstripping or seal as long as the surface is clean...

They make a fairly thick material they use to mount pickup truck caps to the beds. You might want to check with a cap dealer or buy some on the net. It is adhesive on one side and easy to cut to fit.

Any secrets to remove the foam gasket material that was sealed in the track? Acetone?

the old gasket material has to be scraped off with a sharp scraper or razor blade scraper.
then to remove the old adhesive, use acetone or goof off... mixed in a container with about 25-30% wd40... using acetone alone, it flashes off too fast and it leaves you with an unmanageable goo. by mixing it in a container with wd40, and then sponging it on, it works almost as fast but with the wd40 added, it will liquefy the old glue long enough for you to wipe it off...

after getting the old seal off, make certain you clean the surface at least three times with acetone, letting it dry between each cleaning, before applying the new seal.
because you want to make sure you get all the residue of the old adhesive AND any remaining wd40 removed from it...
