Default Gorilla Epoxy & Amazing Goop

Used these products for a recone. Figure I'd share some results.

Ill start with the good.

Amazing Goop



Pros:

- Great for surrounds
- Cheap ($3)
- Seals up very nicely
- Sets very fast (5 minutes and it was good)
- No odor
- Drys Clear

Cons:

- Difficult to work with
- Poor aesthetics
- Too stiff for refill bottles

It's messy to work with if you want your sub to look factory. As you can see from the picture it comes in a tube where you can make the exit hole small enough to work with but not very well. It is thick at room temp so if you want to wipe some off somewhere or spread it out, it doesn't work out. What I ended up doing was working in sections. I would put some down. Spread it out, remove excess from the screw holes and put the surround down. It is very strong, just not really easy to work with.

Would I use it again?

Yes, if you take your time, it can look good enough. Gaskets will cover your minor mistakes

__________________________________________________ ___________

Gorilla Epoxy




Pros:

- None

Cons:

- Bad Odor
- Doesn't dry "hard" in allotted set time
- Hard to work with (explained)
- Price to use is bad
- Doesn't dry clear as stated
- Doesn't seal
- Becomes unusable too quickly

Products comes in two push tubes with nozzles that HAVE TO MIX. If they don't mix, they don't work. Anyone can follow that. BUT If you use the given nozzles to mix them on spiders/spider landing/ dust cap it is not a good idea. They won't mix properly and WILL NOT set and WILL come undone. You have to mix them yourself and then apply them. Doing that makes it messy and doesn't look factory. When you mix it you have about 1-2 minutes before it becomes clumpy and unusable. Does not dry completely clear in some areas. Dried white-ish around the spiders and bottom of the cone. Dried clear on the dust cap. Not sure why since I applied them the same way. It is cheap. Only $6 but not worth it IMO since its crap.

Would I use it again?

Not for spiders or cones.
I would use it for dustcaps since that's the only part that dried correctly and sealed properly.

_____________________________________________

These are cheap alternatives to CA glue but it's worth it to spend the extra money. Ill be doing a few more recones and will being trying out some more products that are easily accessible at Home Depot/Lowes for those who for some reason can't get CA glue.

I've used goop on surrounds dustcaps and under the dustcap to hold leads down.
And its worked great for me.

On spiders I've used loctite 5 min epoxy. The nozzle seems to mix pretty good. It holds up good on former-spider connections. But my subs the spiders are screwed down so dunno how much the epoxy effects its connection to the basket.

Pretty much did the same thing.

It was for an HDC3 and the spiders rings are screwed down so idk how much the epoxy actually did.

Nothing really bad about the goop. its $3 and works great. just hard to worth with if you want it to look nice.

Might add this in but I went over everything with the goop just now since my cone came apart bc of the gorila crap. I bet it stays this time.

People have been using Goop for years, seen it mentioned on forums for a long time. I've used Amazing E6000 which is similar to the Goop. It is thick as well, but if you take your time when applying, it works out well; mine also came with an applicator tip that screws on for more control.

I did the dust cap on this old Kove 15" back in 2012 if I recall. It has lasted for a couple years, still on there solid but finally blew the sub a couple months ago. The E6000 does not recommend use with polypropylene (last I recall printed on my old tube), but no issues yet.

I'll be trying to save the dust cap, and am very curious how hard it will be to remove.

Overall cheap and works pretty good. I'd use it for dust caps without much worry, surrounds yes, and probably most spiders to basket, but might hesitate on the spiders with extreme subs.

i dont mean anything bad by this, but was that your first time with epoxy? i find epoxy to be the strongest glue by far, just takes a long time to dry and has quite a bit of mass compared to CA glue (doesnt matter when glueing the surround and spider but it might matter on a dustcap and triple joint)

First time using on a sub.

I've used epoxy's many times on house projects. I liked it then and will still use it in those applications but for a sub? No

It was good on the spider landing just because it was easy to mix and apply.

But attaching the cone to the spider and tip of the coil was where it went bad. Just wasn't easy to apply, even in small dabs. I would put a few drops of each of the epoxy or whatever is in the tubes, then mix, then attach.

I let the sub sit for 3 days before playing it. 2 minutes in cone detached.
Did I not use enough epoxy? I don't think so but never know.

I do agree the stuff is very strong. Just this time it wasn't.

as far as the mixing tube is concerned I tried it, and trashed it. I use a sandwich bag for my mixing and dispensing. put the epoxy in the bag, mash it all together, clip a spot in the corner, and put it on the frame like a Pastry Bag.
I test fit and get my steps down perfect so I can do everything as quick and as precise as possible before the final fit.
I use a flap wheel on my grinder to prep the basket, then wipe with Acetone and a clean rag.
I have used CA as well, but had a hard time with getting the activator in and keeping the product from blooming when stacking multiple spiders.

Always use Thick Rubberized CA for the spider to voice coil and the cone to voice coil, It's the ONLY product strong enough for these areas.
The Mudduck on eBay sells AWESOME CA glues and activators.

I like the pastry bag idea.

Just using the mixing tubes to apply didn't work for me. Especially since it was a 12 it there wasn't much room to fit my hand and apply.

Going to edit that into the thread.

E-6000 / Goop type glues are my favorite for dust caps if you have time to wait for curing =)
