fish oil capsules and plastic?

Hey guys
I have another question... Anybody ever cut fish oil caps and mix in their plastics?
Or should they just be used as lube after the baits are made?
I have several bottles of them that are out dated

The only thing that I would add would be oil based liquid. whatever you do do not add anything that has moisture in it will explode I am referring to water. you can add fish oil.

Or you can add cod liver oil and anise.

Thanks Guys... I looked it up and the stuff inside the gelatin cap is pure oil... I'll try a small batch putting it in cold plastic... so If it BLOWS UP it will only messs up the inside of my M-Wave
