I always thought that it stood for Water Displacement, and it took 40 attempts to get the formula right. I don’t believe that it’s hygroscopic. I have used it for short term rust prevention. It’s probably too thin for long term.
The problem is it's too thin. It cleans off the thicker oil and grease and then evaporates leaving bare metal. Presto- flash rusting
I’m just happy to have checked this thread having seen there were new posts and an update was actually in there. I agree with Hugger and thinks he makes a good point. I try and purchase stuff from TA even if I can grab it from the corner store and for a little cheaper. Those guys stay in business and so does my hobby. That’s and Ski’s are always good peoples.
I am glad we finally made it. I am pop canning my exhaust so I can at least get to the track once this year. TA's Catalog has a boatload of items for the Buicks you just have to download it This way you have at least a darn good chance of it being right.
If you don't mind adding to the electric bill and initial expense, I would get a dehumidifier for where you are storing/assembling your short block.
mark, use this. good enough for million dollar cnc machines....good enough for that buick boat anchor. lol https://www.grainger.com/product/CRC-Corrosion-Inhibitor-2F143

Taking a quick look at its MSDS, we find that it is >90% hydrocarbons and petroleum distillates, which are immiscible with water, and they report that it is insoluble in water." https://www.wd40.com/faqs "WD-40® literally stands for Water Displacement, 40th formula. That's the name straight out of the lab book used by the chemist who developed the product back in 1953. The chemist, Norm Larsen, was attempting to concoct a formula to prevent corrosion—a task which is done by displacing water. Norm's persistence paid off when he perfected the formula on his 40th try.
