A bit of a rant here. I just started a batch of McNally Frogs and had to resort to plastic bodies. Ugh.

Jann's, Amazon and other places that sell crafts will have the small cork stoppers, that we can use, but I've not seen the preformed cork bodies in years.

Bondo?I guess on bigger poppers.Little poppers I just use foam and a punch and hammer.I made some big poppers with cork but the paint does not stay on well.I like traditional materials.What is the best primer for cork?

thanks trev.I have a very specific design for bass poppers and i can saw balsa to the rough dimensions then sand.I copied this specific shape as i used to buy these premade molded on the hook poppers.Some sort of hard plastic foam.They just worked and caught a lot of bass on them.I got down to my last ones and then could not find them anywhere on line.So i just took some good measurements and made my own.The flymen or whatever they are called that sells the articulated makes some decent poppers bodies in various sizes with matching popper hooks and eyes for each size .I have yet to catch a fish on one but have had a few hits but they spit the bug .I got a bunch of stinger hooks over the winter that i think will work better on these particular bodies which i have many.For the ones i make i use a streamer hook.

the flymen have their doble barrel poppers that have that deep cupping.like those.might be worth a look they are easy to work with.

If you can shape the main shape with sandpaper, you can do the cup with a Dremel tool. But it isn't as easy as buying them.

Balsa is a lot easier to work with, but you really need a decent coating of epoxy. Otherwise, they don't hold up.
