I've been using it a little while now and it seems great. I have made up a plastic bin, with lid, (like a very mini dustbin) of 1/2 gallon and I just throw the reels, swivels and other bits and bobs in for about 1/2 hour and they are perfectly clear. Just dry and oil reels. In fact, they claim if you just let the items dry, it leaves a protective film, but I still oil the reels. I have also made up a spray container (the sort used for 'misting' flowers, etc) which I use for various bits on the boat (knives, pliers, external parts on the engine, etc., etc. Also for the rod fittings.
I would have to say that it seems to do what it says on the can (platic bottle)
