Been curious - maybe you plastic pourers know - what kind of oil covers tubes and plastic baits? Seems like most of the brands I've tried have some kind of oil/grease - I suppose to keep them from sticking to one another.

Wouldn't be WD40? Would it then count as an attractant too, since it's made from fish oil (I read that on the internet [crazy])
WallyWorld seems to be having a PRE-season clearance sale on bunches of fishing gear. Picked up a few extras to "fill" the tackle box, need to get 'em out and rip through the riff-raff! Too bad the N. Marina is closed still.

Still wonder where the Bear/Cutler crappie go to do their spring fling?

Quote:What a Fish story!
Myth: WD-40 contains fish oil.
Fact:
Consumers have told us over the years that they have caught some of the biggest fish ever after protecting their fish hooks and lures with WD-40. We believe this legend came from folks assuming that the product must contain fish oil since it appears to attract fish. Sorry Charlie[size 2]®, it just ain’t so.[/size]
WD-40 Company has taken steps to respect and conserve the environment, and encourages its users to do the same. While WD-40 can be used to help protect fishing equipment from rust and corrosion, WD-40 Company does not recommend using WD-40 to attract fish.

Here is a link to the MSDS (Material Safety Data Sheet) for WD40 showing the ingredients....Yep no fish oil.[laugh]

The "oil" you feel on plastic lures is either the release agent they use to keep the plastic from sticking to the mould, or some kind of mineral oil used to keep the lures from sticking together in the package. Or a bit of both.

As the others have shown, there is no fish oil in WD-40. If you want to use an attractant, buy one that is designed for the purpose. I recommend Gulp.

Rocky, you said "release agent", but I think that is what he's asking. What IS that release agent? I know many plastics that are molded are formulated to sort of make their own oil/release agent, as they cure, just to make this easy for manufacturers, but I couldn't tell you CHEMICALLY what it is.

It's a good question, because, for instance, those ubiquitous plastic bags from the grocery stores are actually coated with a very thin layer of purified animal fat; just cleaned up slaughterhouse waste.

It ain't WD-40, though.

Beats me. I'd suppose that it depends a lot on if they use a hot or cold molding method. It might be something as common as lecithin (Pam), or a light mineral oil. It has to be compatible with both the lures and the packaging, obviously.

It's also entirely possible that they use two different materials. They might wash the lures to remove the mold release agent and they apply a different material for packaging. Gulp products, for example, have a bit of that Gulp liquid in the packaging.

Its known and sold as "worm oil" through the online plastic supply stores such as MFG.CO,INC [url "http://www.pouryourownworms.com"]www.pouryourownworms.com[/url]. Its used to keep the soft plastic from sticking to eachother and its packaging..

Ding ding ding! Looks like we have a winner! "golf clap" Good Answer - Good Answer. Survey SAYS!!!

Thanks for the link. Worm oil, eh?
I have had some plastic bags that seem to disintegrate, I'd assumed is was the oil on plastic reacting.

Sorry guys - I guess I should have put in more Smileys to make it clear I was joking. I know the WD40 thing has come up time and again.

I do need to spray some on my bumper hitch! Displace that water!
I dont know if that "worm oil" is used by Berkly but what ever they use melts through plastic. I accidentally drop a gulp worm in a bin were I keep my water bobbers come next season the worm melted through a few bobbers.

I got a pic on here some were.

The oil used on plastic baits is plain ol mineral oil. You can go buy it at any drug store. You can add your own sents to it, grape, strawberry, garlic, etc. Mann's jelly worms were the first baits that came with the flavored oil on them. Gene Larew was the guy that developed the salt infusing process for plastic baits, he still holds that patent I believe !!

Berkley does not use mineral oil. Glulp and several other of their baits are made from a material that they make. It is plasticized and molded, but is the real thing. You can go to their website and read about it.

As for the melting you see when plastic baits come in contact with certain other hard plastics, it is the plasticizer in the bait reacting with the plastic. It is most common with styrene type plastics, which are usually what older, hard, clear tackle boxes are made of, bobbers, and even some hard baits. They also will react with styrofoam ( styrene plastic).

Always use a "worm proof" box to store your soft plastic baits in, keep them away from most hard, clear plastic, and expecially don't put them in your coffee, even thought some baits are infused with it.
I've seen that - melding of the bobbers, becoming one with a plastic frog, or other congealment.

One thing I've learned about the Gulp gooeys is to NOT let them desiccate on your hook! Word those things get hard! Got the extra juice to recharge the buggers. Fish do like whatever that scent is.

Thanks for the info
IF they do dry out, you can put em back in the solution and they will regenerate. They will do it to some extent in water also. Only problem is the cost, a tub of those things costs $20.00, pretty steep ! Even the small packs are 5-6 bucks, but they work !!
I'm not sure what it is made of, but it is just called worm oil and can be purchased on any bait making website. It isn't mineral oil, that can cause the baits to bleed, shrink and harden. I personally don't use a release agent when using aluminum molds either.

Worm oil is a special oil used by manufacturers packaging and marketing reasons.
IT IS NOT mineral oil or anything you can purchase at the grocery store. Mineral Oil will shrink and harden your plastics. WD-40 will work but only temporarily as it will soak into the plastic. Most of the scents you can buy off the shelf are cut with the right type of worm oil and work well. ie: BANG (custom sports in Hyde Park sells it)
Other than that you can order worm oil from any online vendor that sell hand pour supplies.

In buying lures over the years I have found out that many types of oil is used from Cod liver oil to worm oil...

But never WD40 it eats any plastic bags after a wile. .
And any worm or soft plastic worm will eat or melt some other plastic they get put on (touch) for very long..

Some lure makers have there own sent they put on there lures to or in hopes of making them catch more fish..

I use to buy lures in lots of 3,000 to 5,000 at a time per color..

I know a fella that soaks his senkos in water days before a tournament, don't think he does any better than the rest of us. I cover everything with smelly jelly, sometimes even in the bait bags. Learned years ago to leave plastics in the original bags. On the way to brown lee res I'm giddy.

I don't see what the water would do to help any..[crazy]
