ok, guess i'll start.
almost everything i know comes from posters on this board or others. i don't have vast experience, but i'll let you know a few products i have come to rely on.
wipe-out foaming bore cleaner. i simply love this product, and if there is a better way to clean out your barrel, i haven't found it. i have not had to use a brush on a barrel in so long i can't remember!

you simply spray this into the barrel, wait 30min or so (or clean up the rest of your gun). run some patches through and clean barrel! sometimes i have to spray it is twice, but it is still a breeze. made cleaning my guns much more enjoyable imo. i've only had
one problem with it. once, it discolored a small part of the stock on one of my guns (of course this particular stock was very cheap and soft). so, if you get it on a wood stock, wipe off immediately.
birchwood casey lead removing cloth. FOR STAINLESS ONLY, i have been told. the poster vincent led me to this product, and it works!!! i have a stainless revolver that i had scrubbed to death trying to remove some lead burn rings. this baby just wiped it right off! this just works!! boy, does it stink though!
slip 2000. probably well known, but a great lube for the semi autos imo. it just seems to get better after an extended shooting session.
the rest of my products are fairly common.
hoppe's #9 as a general cleaner,
rem oil as rust prevention.
i would like suggestions about the best general protection for storage of firearms. i also like hearing suggestions on the best products for blue vs stainless firearms. especially what products might be harmful to certain surfaces and finishes.
