Paul, I've always made my own. I wasn't aware you could buy it commercially.
I will be the 1st to admit that the initial batch is a bit spendy, if you dont have any 'left-overs' to start with.
Likely the most expensive component will be the Anhydrous Lanolyn, but that is an optional ingredient anyway.
When I make a batch, I make well over a gallon.
And, luckily, I discovered a long time back that you can buy little 'Travel Bottles' from Wally World that are very inexpensive and work great for all those "buddies" you suddenly find yourself with.😇
Yes, I wipe the bore, and everything metal I can get to without disassembly at the range.....then, after I get home and actually clean the gun, including the lock, I let the gun dry good, and wipe everything down again with Ed's Red.
Kees can tell you, there is just nothing better for this purpose!
A bit of a pain in the "you know what" to put together.
However, you will end up with enough lube/protectant to last you for years, and if you have several grandsons in their twenties, and each with their own collection of guns, it will cut down on them stealing yours, every time they "just stopped by to see how your doing".
Anymore, when my grandkids 'just drop by', I make them keep their hands in their pockets before they go inà the shop.
Ed's Red, its hard to beat!
I'm sure there's plenty 'good stuff' on the market that you can buy that may work just as well, without the hassle of making Ed's Red.
I have tried a lot, if not most, and I have never found anything that will even come close....you need to Google... Ed Harris, he knew a little bit about shooting cast too.
