    I've gone through thirty pounds of the stuff in the past two months.

    So far it's the best way I have found for a number of reasons, the industrial powder is cheap, like $2 per lb. It doesn't smell, it doesn't burn you when you get some on your skin, I have found it doesn't flash rusts as quickly the way other acids do.  It's also very easy to dispose of.

    I'll have to try some salt with it.

  2. Back in the summer there was a thread about a German product, a paste made of Citric acid and sawdust.  I can't find it at the moment but I have been playing around with Citric acid for a couple months now and it has become my go to rust remover.

    I have found all the other acid rust removers have some drawbacks to them but Citric has the fewest so far.  It is very inexpensive especially the industrial grade,  I didn't want to purchase 50lbs until I knew it was worth it so bought 10lbs of food grade.  2 cups of dried powder in about a gallon of water makes a strong  solution. Your results may vary depending on the hardness of your water but it should be easy to repeat these results.

    The test piece is from the KA24DE engine I'm using in the 510,  2 cups of Citric acid in a gallon of water, all I did was scrape the worst of the flaky rust off.  The shop is cold, just above freezing, when the water is room temp in the summer rust removal happens a lot faster.  If you splash some on your skin you just rinse it off, there is no drama, no burns.



    These next 2 pics are after 20hrs soaking, took it out of the bucket and scrubbed it with an old wire brush and rinsed. The last 2 pics are after an additional 24hrs.

    Now that might seem like a long time but I have lots of that so I'm good.  Muriatic acid is 10x faster for sure but I have never found a way to completely neutralize it, the rust always comes back under the paint,  so far that has hasn't happened with the Citric acid pieces.

    If you cross the border into Canada, it's two weeks' quarantine, no exceptions, no excuses.

    Unless of course you're filthy rich, then you can just breeze right through,  https://www.cbc.ca/news/canada/liz-uihlein-covid-19-diagnosis-1.5801118

    The area where I live in the province of Ontario is right on the verge of a lockdown at the moment, we hit 1600 new cases in one day last week.  They say once we hit 2000 per day then the Bell curve takes over and then it will just skyrocket.  I'm just going to have to kick the breathing habit.

    I could easily set up a different dystopian novel around the fight for access to the rare metals needed to support the use of electronic devices and transportation, and that novel could be set in the next 30 years.

    That's one of the reasons why we're heading back to the moon,  despite the agreements that were signed 60 yrs ago about no country claiming mineral rights or territory on the moon, you can bet your life that if a cost effective way is found there will be mining.

    That's a $250,000 car.

    Funny, but Pierre Z worked on it prior to the auction.  He worked on the 31k mile Z.  Did you put those wheels on it?

    I did, they are Appliance wheels as I remember.

    No wipers! 8 owners and no wipers. LOL


    The car is in Cali now so who needs wipers?  It certainly had the original wipers when it left me.

    We see quite a few of those here at classic car events - a Z parked next to one makes it look positively dated! Only 3000ish were sold in the US so I imagine they would be very rare over there. Sadly the 2.5 & 3.0 V8s weren’t the best engines for reliability, so I can imagine in a market where V8s are a staple diet, it was left wanting. They do sound great at full pelt though!

    With the hard top I think it is just stunning, as elegant as a Jag, but as a convertible the B pillar wrecks it for me. It looks clunky.
