A more available substitute for Testors Light Battleship Gray?

First post, so please excuse me if posted wrong.

I do a lot of model building and my main paint used is Testors Light Battleship Gray. As you know it's only available at hobby shops and only in small cans.

I am asking if anybody might know a more mainstream substitute color made by Krylon or such which could be purchased at Lowes or Walmart maybe. Thanks for any help

Try LIGHT SEA GRAY (FS 36307) 3oz. Spray Can Testers[/h]
Testers pulls this up when you look for Light Battleship Gray in a rattle can
