You know a 7th Grader that's been a Field Engineer for 30 years?

In the drafting room it used to be pretty common to have a new hire show up w/ 10 more years experience than they were old. That 7th grader puts that record to shame.

Just a statement of how smarter our kids are than us parents.... while I was able to set up a VCR clock for my parents years ago, my kids can chat, IM, text, cut & paste, download, third party share, twitter, podcast, and other things that I have no idea what they are doing....

Now, if I could just get her to make alot more money than I do - I wouldn't have to worry about MY retirement!!!!

My youngest daughter went to Berkeley and then got a law degree at NYCLS. She married an investment banker (CitiBank NYC). My daughter represents foreign industrial clients before the Supreme Court. She and her husband made more money in one year than I have made my entire life. No BS. She retired in her thirties.

The part that makes it interesting is that my daughter never finished high school. She has a GED. She ran away to Honduras when she was 14 years old (Tegucigalpa?). Took a while to find her. I thought she would never amount to anything, but I was wrong. Me? I have two engineering degrees and almost had a chemistry degree. Nice pay, but didn't get rich.

I doubt that I will ever get a cent from my daughter, and wouldn't ask if I was starving.

The soap idea is a good one, regardless of its origin. Kinda like the best rust remover for firearms I have ever found is black molasses. It doesn't etch the metal.

I had a tip a while back about rust removal
inetogether : Jaguar E-Type : Molasses rust removal (25 June - 3 July 2006)

Question: If (as the articles suggest) the operative solvent is weak acetic acid formed by the fermenting molasses, has anyone looked at just going w/ vinegar? (Or does the molasses' sulpher content place a part?)

[Jim Tarleton]

Fermentation will produce many acids (and alcohols), including proprionic, acetic, buteric, and other VFA's. Although the process produces acids, it is generally anaerobic in nature, with an alkalinity ratio around 0.2 to 0.5 typically with a pH slightly greater than 7 (7.4 to 7.8).

I think it is the combination of the many different reactions with the iron oxide, oxyhydroxide, and other iron forms being consumed in redox reactions and converted to soluble and insoluble forms of iron. Iron sulfide (FeS) is a strong possibility as an end product that would be insoluble and stable. I have never detected the rotten egg smell, so hydrogen sulfide (H2S) appears to be absent.

It is an interesting process that works, its cheap as all get-out, and works better than almost any commericial rust removal process that I know. The only draw-back is the slowness of the process and your cows will consume it if they can get to it. I have never tried to understand the chemistry of the process.

Some processes defy interpretation. Stick two magnetized nails in two candles, wire the the two nails in series to a flashlite bulb, and when you light the two candles, the bulb will glow brightly. This one always left me a little amazed also, but it is an excellent source of light in a storm. Four or five setups on a kitchen table will light up an entire room. You can keep reloading when the power is off!

As an individual with "car restoration" as a "second hobby", I can tell you that not much beats a sand-blast booth for rust removal....nothing chemical at least. For "delicate" work, walnut shells or baking soda works wonders with little or no "collateral damage". It's cheaper than molassas without attracting flies into the shop!

I have priced blast cabinets, air compressors, etc., and no way are they cheaper than $12 worth of molasses!

I would love to see your old cars. I can't afford them, but I could spend all day looking at them.

I do agree with your assessment as to the flies.

Maybe....but then I've had both for several decades! 12 bucks-worth of walnut shells or baking soda is more than enough for my small cab, and can be used for months versus the "one-shot deal" aspect of the molasses, not to mention that in my case....I have to be able to paint the offending part when I'm done de-rusting. I have to be able to get that sugary goop off the part in a way that allows me to do that....meaning that washing with water is counter-productive!

PM me an e-mail address and I'll send some to you!

Back in the Dark Ages when I was working for Air Products & Chemical Met Systems Div., we had an operation in Transfer PA that was briquetting ferro-alloys using industrial molasses by the ton as a binder. That crud was ALL OVER that building in multiple stages of consumption/decomposition....like a nightmare food-fight at a Waffle House! We used to come in to work on Sundays with .22's to do a little "on-the-clock" rat-hunting!
