I have lyman pro 1200 tumbler I use corn cob media. It cleans the brass good
but does not polish it ,its very dull, do i need to use some kind of additive to make it shine.

There are various brass polishes you can add to the corn cob media, Cabela's, Midway USA and other sites have them or you can just use a liquid car polish. I have used Nu Finish auto polish and the Cabela's metallic cartridge polish and see no difference between them. Add 4 capfulls to the corn cob media and run the tumbler for about 15 to 20 minutes to get the polish all mixed in good and there are no lumps left. Then add the brass cases and run the tumbler until you get the cases all clean and shiny.
I have not used corn cob media, instead I use lizard bedding from Petsmart, it is made of crushed english walnut shells.

I know many people like polished brass but I believe that what you want is clean brass not polished.

David Tubb in his video "High Power Rifle Reloading" states that he only cleans his brass every 3-4 times because he feels that a "grippy case" works better. Of course that's just his opinion.

Also don't forget that whatever you put on you cases to polish them is likely to end up in your rifle/pistol action. Additionally adding polish to your cleaning media may result in what I call the "mop & glow" effect. That's where dirt gets sealed into the polish and builds up over time.

Not sure if I have ever heard of a mop and glow effect, all I can say is I have used a couple of caps of polish in my media for over 40 years and I clean my guns after shooting them. There is no polish on the planet that will withstand bore cleaner. If there is please let me know as I would like to use it on my car:) I like my brass polished but in reality a good cleaning is all that is needed and some will even disagree with that.

A long time ago there were some guys here that turned me on to nu finish, and that works great.

Then more recently I saw that some people were doing a capful of nu finish and a capful of mineral spirits. If you want some majorly shiny brass give that a shot, it won't disappoint.
