Actually I've read in a bunch of threads where people have used it. Fast cure in the big tubes that fit in caulking guns.

did not know that... i haven't ripped a tray apart, but within the engine compartment I used thickened epoxy filler, then layed glass over it while the filler was still damp so the two chemically bonded together.

should I use it on the bond line in the engine compartment or just use a layer resin? to seal it up. I dont want to faom my bondline before I reinforce and have it leac and waterlog that foam....

I wouldn't use 5200 in the bilge.
Water leaking into the sealed tray area is a problem, the bilge is easy to get to any time.

I used 5200 to try and seal up tubes in the bulkhead... 3-4 days later it was all at the bottom of my bilge and hardened...awesome!

5200 for the loss.... i used to swear by that stuff.. now i hate it

no matter how neat i am with it-it goes everywhere.

even the fast cure takes a while to dry in cold temps.


it has its place but i say not where you are using it..thats just my .02 though.

thickened epoxy in the bondline should be plenty...imo

first brush a thin layer of epoxy in the bond line then foam the bond line under the hood and sand it smooth then lay glass over it. I also use fiber filled epoxy on the bond line in the tray area I was never a fan of 5200 unless it's an emergency. Wal-Mart in arnold had the 5200 fast cure.

Correct me if I'm wrong, but I didn't think there was a major problem with the bondlines around the engine compartment leaking. I know for my SN, the major problem was inside the back of the hull. It looks like the factory poured the foam into the top half and the bottom half of the hulls separately. Then they glued the two halves together foam included. However, from what I noticed on my Square, they didn't bother to shave the excess foam that leaked onto the bondline area when they poured. They then proceeded to put their glue over the foam on the bondline and mate the two halves together. I'm positive this is where the leaks were coming from on my ski. I could easily see the foam wedged up in between the bond line with glue on top of it. I would hope that the engine compartment wouldn't have as much of a problem with this because there isn't any foam up there that a lazy factory worker should have shaved off to get a proper bond between the two halves. I guess you just hope they ran a continuous bead of sealant all the way around.
 
Its a mostiure cure product made to set underwater. I only use fast set anymore.:headbang:

the non-cure 5200 that i used was on a kneeboard. the 2 skegs ripped off so i fabricated 2 pieces of plastic to replace them. held them on with 5200. even after a few uses in the water, it never cured.

IF i use 5200 anymore, its because im in a bind, and its fast cure only. with that said, any BIND that would require a 24hour wait time isnt really a bind at all and epoxy could be used instead.

There is probably very little moisture in the air due to winter time/cold temps, so it's going to take forever to cure.

Maybe try a warm humidifier in the room to help?

I always figure that i am better off using epoxy in almost all cases. Vary the thinkness and use the right matting and you're golden. In never gets warm enough in Michigan for either fast or slow cure to be an effective solution use 404 microballoons

Use 3:1 epoxy with a lot of micro balloons to fill the bond line, it sands real easy before laying your reinforcement on top.
