Foam pads, cases...
I, for one, do not understand the big problem with gun cases or pad style systems.
I used Plano & Docksil type cases for handguns since the early 1990s w/o any problems. I also use Bore-Store treated bags & I clean-lube my firearms.
The only thing I ever saw was a slight bit of CLP seem into the foam or stain it. For a $5.00 or 6.00 plastic case, it's no big deal.
In 2013, there are many cases, safes, gun socks, kits, CLPs, greases, etc to secure/protect firearms.
Just check them often & dust them off if displayed in the open and you'll be okay.
Every 2nd matters.
