Kroil for rust prevention?

Curious if Kroil is good for the final step in bore cleaning for rust prevention or if a different oil might be a better choice? I know the Kroil is sometimes used in conjunction with JB Bore Cleaner to clean the bore. I guess its properties for penetrating the steel aid in the cleaning process. Just not sure on the properties for rust prevention.
 
Something else related for discussion. Concerning the new Thoroclean and Thoroflush, are these really new bore cleaners or are they just reinventing the wheel from Kroil and JB Bore Cleaner? They seem to be very much the same to me. Not sure which one might be better.
 
I've used it for years, but... couldn't prove it's better, however, it seems to work for me. Many of the Palma, F-Class, Military & Swat snipers guys I've known over the years have used it as well. I still use it. 😉 🤙 Cheers

Addition: I should have mentioned "only" in the bore. Frank in the Laurels is correct.

..if it's a hunting rifle just don't use it...it'll gum up your action slicker than -hit....especially the trigger....I found out the hard way in season...
I think I saw on another thread where you recommended lighter fluid to clean it out of a trigger mechanism. I'm usually pretty neat about cleaning my firearms though. I don't get a bunch of cleaners slopped where they don't belong. Always use a bore guide. Only thing I would be concerned about is if you had left extra in the bore and stored the rifle upright. Possibility of it running down into the action. Still point well taken.

It took many many cans of lighter fluid to cut and dissolve Kroil when it thickens... great cleaner for my PPC's, BR's and Dashers, bench guns, but I won't let it touch a hunting rifle again...
 
For at least the last ten to fifteen years I have been using Eezox on all our rifles externally and in the bore.
All our rifles are blued CM barrels and actions and we have had no corrosion issues even with our high humidity environment.

It's a penetrant. I use it as a part of the cleaning process only. I use Clenzoil as a final step and protectant.
