Hey George, I have been laughing alot at all the times you have said bondo is not an adhesive. I was just wondering how does bondo then adhere to the fender of your car or anything else you stick this stuff to. I guess for not being an ahesive it sure does BOND O so well to things it is put on. Sorry for this but I think you have ran that issue into the ground. Jack F

Why do we cut and reattach forms with it--if it is not an adhesive. If you get your ears good and dry you don't have trouble with drumming. I've had good success competing with bondo ears. I tried the ear magic with drumming every single time. Just my 2 cents....
Bondo is NOT an adhesive when used in ears. It does not stick to the ears well at all. Once the bondo is hard I can pull it easily out of the ears. I have done this many times. The reason bondo can be used to put forms back together is the fact it is a rough dry surface. When you use bondo on the body of a car doesn't it require sanding? I guess I must side with George on this one.

.....To put forms back together, because you generally are usnig the form right away. The skin and hide paste will make the job perminant. Put that form together and hang it on the wall for a couple months and the slightest bump cancause it to fall apart. Sometimes it doesn't take a bump, it will let go on its own. Been there, done that.
Bondo is not an adhesive. It is a filler. Although it will adhere, it is not intended to be applied to surfaces that are not completely dry. solid, or well sanded. Bondo will not stick to unsanded paint, glass, or other smooth surfaces. When used as an earliner. Bondo actually only works as long as the skin remains in contact with the bondo until Both are completely dry. At which point the ear skin is dried into the position of the bondo. It takes very little to separate the two. a true adhesive creates a permeant watertight bond between the two. Bondo holds forms together, because the polyester resin saturated the spaces within the foam, and holds them together.
Stick velcro together and you can pull it apart easily. Now stick it together then try to "stretch it" apart. Requires ALOT more power to get it apart this way, depending on the size of the velcro patch. Same way with bondo. It will withstand up and down pressure but will pull apart easily, and try to put a form back together without punching hole in the foam first.
Now one of two things: That was the DUMBEST question I've ever been asked OR, you've never done any body work at all. Bondo "adheres" to fenders because it is ATTACHED. You either drill holes in the fender or install rivets/screws to attach it to the fender. Bondo is body FILLER just the same as lead once was. In my younger days before Bondo, we repaired all our dents with LEAD. It was troweled on over the dent, affixing itself just like Bondo. It took several applications usually and when it chilled, it was rasped off and then sanded, primed, and painted.
Bondo STILL depends on a "tooth" to hold it in place. It holds mannikins together by imbedding in those tiny nooks and crannies of the foam. IF you want to use it for an earliner, it will hold as long as the skin fits and doesn't dry in a drumming method. Otherwise, you're out of luck.
Just do this one task and prove how wrong I am. Do one ear in Bondo and then do the other with Ear Magic or any epoxy with chop in it. Let cure. Then you pull out both earliners. See which ONE is ADHERED to the hide. The one that comes out is not an adhesive.
I'm sorry I couldn't resist geting this one started. I realize it is intended use is a filler material that bonds to the area needed to be filled. In bondo ears I would ass-u-me it works so well because of the texture of the skin. I have yet seen a perfectly smooth piece of skin on the inside of an animal ear especialy after tanning. Every one has something for sale. If you properly prep the area needed bonded it will bond. Latex caulk sticks to smooth porcelin tiles and toilets also works great for holding ear liners in place if done proper. Liquid nail I bet would work as well for a bonded ear method. I haven't tryed it yet but I will some day. George I knew this was a dumb question when I put it out here lol. Just thought I would stir some good comments. Take care guys and gals I have to go fight crime for 8 hours. Jack F
Car bog is what we call it in Australia. Most any thing will hold for a time but taxidermy should last for many years and bondo will let go and it will drum, but you will have bin payed by then and if your not in the game any more you will not have to fix. For free ether, If you wont it to work better after the bondo sets take it out,of the ear and ruff it up good and glue it in, this is a good way to make it work for odd shaped ears but for ears in good nick ear liners work better.I am doing a repair now on drumed ears on a fallow dear 10 years the job lasted it was tin aluminan sheeting and yellow glue it split the ear all the way round, and some will tell you it a good way to line ears any ,way its good money for me and an esay thing to fix.
Lets call it STICKO from now on, but it still drums, plain and simple. I see that all the time with bonded ears. Its just a fill method, liners are far superior. If you think the ear magic is drumming, think again. You put it on the BACK side of the ear, and its the FRONT side that drums. How is it the ear magic drumming? Its the fact that you arent shaping the ear accurately. Will the wonders never cease? Oh well, at least these posts are fun! Jack, see what you started? hahaha
If you could see the smile on my face. I knew it would bring joy to most who read it. I see alot of scutlebut on here and think some times we need to get something going that could be fun and not damaging. I need some of the ear magic to try. Also how long has it been used? I hate drumming! I think it drives all of us nuts LMAO. Take care Jack F
