Bulkhead Adhesive/sealant

Postby paulf » Fri Jun 09, 2017 12:17 pm

Hi there,
I have a 1998 Current Designs Slipstream fiberglass with plastic bulkheads which are leaking and loose. I removed one quite easily and have been assuming that someone long ago attempted to reseal the bulkheads with clear silicone and a lot of it.
But now after actually removing one of the bulkheads I am thinking that everything may be original here and that maybe Current Designs used some kind of clear glue at the factory. Please see pics as no other colored or previous looking sealant is visible. Just a lot of the clear caulk. Same on all other bulkheads. So my question is...am I dealing with silicone or am I getting lucky and just a factory installed glue? Any help will be greatly appreciated. I have purchased a tube of lexel.
Thanks,

Paul

Gluing plastic is always a bit of a bear.

When I contacted Prijon and asked what I could use to glue to their blow-moulded plastic hulls (everything I had tried had failed), they told me the only thing that would work is "GOOP" that is not available in Australia. I ordered some from the States off eBay and it worked like magic. I now use it on all sorts of things that are hard to glue or need a flexible bond. The bond is strong, but not strong like epoxy, but it stays very flexible. It has worked well re-sealing the foam bulkheads in our plastic Prijons.

I needed more, and found that the same company has a different product called E6000 which the manufacturer told me is essentially the same product (I've found it to be less viscous). It is used in hobby crafts and is readily available in Australia on eBay.

I see that GOOP may now be available in Oz, but looks expensive: https://slhobie.com.au/gear/mounts/485-goop

I called CD and they claim that in 1998 they used GE 1200 Construction Silicone. I could try using the same thing again but since I need to remove as much as I can of the old silicone I may use Lexel as many people on this site seem to recommend it. I may be over thinking this but I want to do this job only once if possible. Not looking forward to trying to get the old silicone off.

So...I have removed the silicone down to a thin film still on the hull.
Does anyone recommend going with silicone again or Lexel. Thanks for you help.

When using silicone, I've always gone with choosing sixaflex ( spelling not sure sounds like that). Was told years ago better bonding. No idea what Lexel is, hope someone can expand on that, I'm taking on buckets per hour in chop.

Excellent stuff, superior to silicone for Kayak use. Sticks like the proverbial to a blanket and recommend you wear gloves. Cleans up with metho.
