Default Adheasives & Epoxys

Always have wondered, if the adhesives found in stores like W-mart and others is ok to use....The CA's seem like the same ingredients and the epoxy may a little heavy. So question is , is it fine to use these or wait a week, in my case , to get some delivered. . . . . .. Mainly was thinking about the fuel from the plane reaction etc. gphil

gphil, This is just MHO, but I have an instant distrust for the quality of ANYTHING coming from Wally World. I wouldn't use their glues on a plane of mine. Now, I am aware of the problem you have living in rural Georgia and a local hobby store just doesn't exist (there aren't any in Villa Rica Georgia either). We have to plan ahead and "stock" the needed supplies ourselves in order to have them when needed. Some visitors say my shop looks like a hobby store because I have pegboards full of all kinds of model hardware, fuel tanks, motor mounts, landing gear, wheels, spinners, pilots, prop nuts, you name it! I stock asst CA's, epoxie, fuel proof paints, engines, kits, ARFs, receivers and radio sets. Sounds like I have it all, well I still sometimes get caught short and still run out of something, but like you I have no LHS to run to so having on hand as many supplies as you can afford to stock will keep you from having to wait for a shipment most of the time. Now back to your glue question....If you have a craft store such as Hobby Lobby near you, I have bought and used their CAs and debonder with success. I have not used their epoxies. I have to go to the next town over to even have a Hobby Lobby, you may have to go to Athens or Anderson S.C. to find a craft store or maybe even a Hobbytown USA. If you can't source what you need locally I would wait for the right stuff to be shipped.

Funny the perception you only get quality for a LHS and not a non hobby store,,,, I buy my Epoxy "devcon" from Lowes,, It's well documented the Great Planes Epoxy goes bad on the shelf.

I bought a bunch of "no brand" CA off ebay years ago, it worked and lasted fine,, never seen CA at Walmart,, I may try it

A million guys, a million opinions - and they're ALL probably right in one way or another. Just for giggles, here's mine: Just over the past winter I built/rebuilt/restored 4 planes, 1 was over 40 years old and had just come apart in front, the other 3 were just crashed bits & pieces of old planes. All are in the air again and doing just fine. Glues came from Lowes, Hobby Lobby, Wallyworld and my local hardware store - no LHS anywhere close to me. For the most part, Devcon 12-hr or 5-minute from my local hardware store got the nod (and always does) for where I needed epoxy and regular glue duties was handled by Titebond-II from Lowes or my decades-old standby, Duco cement, from my local hardware store. Yeah, it's ancient but it still works just wonderfully as long as you work it properly (gussets, etc). Loctite "Professional" (LOL, that's the name, not the "quality") CA from wallyworld got the job done just fine where I used CA.

I, personally, don't know or trust Gorilla anything enough to put it in a plane.

But, this is all just me.

1974-built CG Sr. Falcon, front end came apart from age:

1986-built CG Eaglet - vertical crash:

1974 AFI Super Monterey - vertical crash:

1961-built Scale Lines Great Lakes biplane restoration:

NEW BUILD - 1966 SIG Stratus pattern plane - just now covered, about to get color dopes:

I've used various carpenter's glues and CA's from hardware stores with no problems. All brand names, so whether you get them at Walmart or somewhere else won't matter. When I can get something from an LHS I do, because it's great to have one around and it's worth a bit to help them keep going.

I agree that if you are buying a known "brand name" product then it doesn't matter what retailer it came from, but it was the "no name" or "off brand" of unknown quality product that I feared he might get at Wally World, and lord knows Wally World has lots of those. And BTW, it has NOT been well documented that "Great Planes epoxy goes bad on the shelf". It will cloud up over time and just needs to be heated to bring it back to normal for use. No strength issue has ever been shown with G.P. epoxy after it clouded up, then was heated and used. It's fine. Different guys heat it to clear it up different ways; some use short time a microwave oven, some use a pan of hot water, and I have even just set it on top of my shop space heater for a while in the colder months. That quirk has no effect on the product after it is used and hardened.

I buy my CA at Wood Workers Emporium in 8 ounce bottles, It's cheaper and fresher then what I find in the LHS. I have also bought Ca and Epoxy at the hardware stores and even the Dollar store. Not a nickles worth of difference that I have found. I have seen CA advertised as triple distilled or filtered?? Who cares, the formula is the same.
The only bad CA I have ever gotten was some Pacer I bought at an arts and craft store, it was on the shelf so long it was already turning yellow. I needed it right away so I bought it, got my project done and a week later it hardened in the bottle.
I have just never seen any of the bigger bottles of CA or epoxy in any of the hardwares or marts so I don't bother buying from them. I did need a touch of CA to finish a plane and bought the little tube of Gorilla glue CA, it's just CA but the price for that little dab of glue was a rip off.

I use epoxy, CA and Gorilla glue from W-mart. Works great, hasn't been sitting on the shelf for long and the price is right.
To lighten the epoxy, I use micro baloons, still super strong and it won't break in the same spot again.

Everybody has their own opinion, I had great experiences with the 'cheap stuff'

I've got 3 bottle of Zap CA that won't stick one pink (open), one pink (fresh opened) and one green (open). Must have gone stale and maybe some kicker will get it working. Had to go down to the hardware store to buy a couple of 3ml selley's superglue's to do the job.

Normally haven't had a problem with the Pacer CA stuff but I'll open the bottle in the LHS and try it on some scrap before I walk out with it.. Their epoxy seems to hold up well even if it needs to be heated up to decrystallize it sometimes...

I buy my epoxy at Wally World all the time. No probs.
I have glued wings using Elmer's white glue. Unbelievably strong.

http://en.wikipedia.org/wiki/Cyanoacrylate Adhesives found in the box stores are not the same as those sold for our model application.
