Hey Bob,
The house in Florida is only a mile from salt water, and sunset causes a breeze every day...it can be a bay breeze from Tampa Bay or a Gulf Breeze...but based on where you live, you know what's next...
Charcoal grills, patio sets, and anything ferric lasts on the order of 3-4 years no matter how gentle you are with it. Soooo...I read one day about orthophosphoric acid being something that was really neat at arresting any existing rust, like stopping it dead in its tracks when you let it dry for 24 full hours before trying something else. (It apparently pickles a micro finish and the ferric part can't breath any more and is passive). Commercially, I bought something called OSPHO for maintenance on all my outdoor stuff. It not only worked fantastic...it is now going on 3 years on the patio stuff and no signs of encroachment (that does have a Rustoleum Appliance finish now), did it without painting on the b-b-q cooker, and have used it as touchup on the non-cooking surface of my gas griddle that sits out all year.
Then there was a period where there was a lot of blow...a lot of mist swirling about and all of that made its way around the garage door ends...and everything in my garage that possibly could have then flashed off fuzzy since we were up north and it cooked for months, including the tools in the back of the Hack. Solid fuzz?...orthophosphoric acid?...what would happen is I did NOT wire brush the fuzz and just brush painted it with OSPHO? Everything now looks like it was black oxided! (It sort of was....I think). Some grew a white fuzz in places after drying, but apparently that wipes right off as it has not returned and the spots are still black. I have subsequently wiped everything with an oiled cloth, but as aggressive as the area is, everything totally still at bay!
I doubt that it is a durable finish without further painting, but my experience is it looks pretty good for stuff that just sits in a box. I'll shoot you a further picture when my 1915 tool set gets done, I'm just waiting for my tire irons to arrive from Australia, and my era square shank screwdriver that got delivered to the Florida sons house, that I want to include in the picture...
BTW...I was going to leave the double barrel tire pump tarnished for Steven to polish later? Dan T. got me curious on this stuff called Flitz. Holy Cow...that crap works in about 2 seconds...then lots of water flush...then a 5 minute polish with the Flitz paste. THAT stuff is AMAZING on brass! Funny, didn't do so well on the copper plated oil can. Better than when I started, there is shine here and there, but no amount of effort is going to make a transition like it did on the brass.
BTW2 orthophosphoric acid (OSPHO) is mean stuff so follow the label if you decide to try. I let it dribble from the brush over a 45 year old driveway and didn't notice til the next morning. Those dribble spots look like brand new concrete, and I zapped them with Ammonia to kill any further chemical reaction...
