What to use for doping speaker cone edges?

[MadAsAHatter]

I've been searching, but can't find a definitive answer.
I just bought a Weber 15" Alnico Blue Dog speaker that has no dope on the edges. I'll try it as is first, but since I play with higher gain I have a feeling I'll want to dope the edges to control cone cry.

After searching for several days I've come across stuff on what dope is, the purpose, stupid jokes about drugs, etc., but nothing about what to actually use. The only thing I can find on that is half assed DIY hacks using diluted Elmer's glue/modge podge, liquid electrical tape, rubber cement, gasket sealant, and flex seal. None of that seem ideal as most will likely dry to hard and become brittle. Most of those discussions are over 10 years old too.

The closest thing I've seen suggested that looks like it may be a viable option is clear roof sealant since that stuff stays tacky and flexible, but I can't really find anything that says this is the best option. Plus since I'd only be doing one speaker I only need a little bit, not a 25 gallon bucket.

So, can anyone tell me what I can use for doping that's the same or comparable to what is used at the factory?

I buy my doping in gallons so I'm no help to you for where to get smaller amounts...sorry. And you're correct on the cone cry issue with un-doped cones.

IDK if it's the same "dope" as what they use on speakers but model airplane guys used to use dope/doping on the sort of paper that they'd shrink onto the balsa wood wings skeleton on gas powered model airplanes many years ago, my dad had a jar of it in the basement for years...may still be down there !

There is a recommendation there, corona dope looks promising. You can also contact Weber and see what they recommend.

I took me a good bit of searching to weed through all the junk but I finally found a couple of things that may work.

Side note... I either really suck at google or their search engine is complete crap. Anytime I try to look up something I get handed a bunch of old, outdated, useless TGP discussions. FU TGP and your useless topics on how handle material affects combo amp tone.

Okay back to the topic at hand
Here's what I found. Links below Do any of these look like the right stuff?

Parts Express Speaker Repair Glue - A Q&A answer from the staff says it's similar and can be used to dope a cloth surround
Parts Express The Wet Look - Review pictures show people coating the entire cone with it
Simply Speakers Speaker Repair Adhesive - There's a video from them where the guy uses it to dope the surround when repairing a JBL speaker
Acoustic Research Cloth Surround Sealer - found a few vintage audio forum posts that say this stuff is excellent

Lastly I contacted Weber and CJ said he usually recommends a 50:50 mixture of rubber cement and Acetone.

Wouldn't a silicone base be a better choice?

Scrape your pipes, resin makes a great durable speaker dope.

Well shit.... doping the edges is probably a moot point now. The speaker was delivered yesterday afternoon and was not in excellent condition as described. It had a hole in the cone and other worn spots on the edges. So I'm either going to return it or have it professionally repaired. Either way I won't have to bother with doping the edge myself.

That’s odd
I searched through iPhone and put in yahoo
And this is what came up. I agree. When I tapped the link nothing came up.
