I’ll be doing more research in general. I’ve already collected some comments about this and that product.
 Yes, auto restorer’s have been using this stuff for years. I have not heard of or read any bad reviews of this stuff.

This is still “on my list”. Don’t know exactly what my approach would be, but I’ve decided it’s a good product.

 I’m sure when the time comes, as long as I haven’t started dismantling the truck, which at the rate I’m going with things, won’t happen for a while, you could bring it down and put it on my lift to do this job.

That would make things easier, thanks.  

 As you have figured out though, any type of oil or “sticky” stuff is going to attract dirt to stick to it. This does not harm you but the guy that has to work on it won’t care for it. Make sure there are no statements in the corrosion warranty that will disqualify you from making a warranty claim for rust. Chances are though, you won’t need to before the warranty is up.

There’s plenty of stuff around that qualifies as sticky, according to my research. The best piece of wisdom thus far from my research is to use something for rust prevention that has no stickiness at all, that is totally dry to the touch and can’t attract anything. I will be sending you some very interesting “finds”, and you may or may not know about them. The next round of quotes (once I get done editing them) has some interesting things to say about WD-40.
 Yes, we get it at GE in 55 gallon drums. The floor people fill hand pump “WD-40” spray bottles with it.

Basically it seems people’s success comes down to their expectations and how they use it. Frequent users in dry areas indoors do best. People using it for any other application and/or infrequently have poor results. It would appear what it’s really for is displacing water initially, then once the water’s displaced you use something else to accomplish a particular task. I’ve read the history on it, how and why it was originally developed in 1952, etc., the formula. Displacing water is it’s biggest “success” as an application. Once it dries it leaves essentially a mineral oil residue, which is why I’ll never use it on my car anywhere. Looks like a very poor candidate for the bottom of a car, unless you were gonna wash the bottom then spray it every 2 to 3 months, more likely monthly. Then it would actually inhibit rust to some extent.

Someone did a very good test of a bunch of stuff. Along with that, my other research comes down to 2 really good candidates for the bottom of the car, and fortunately they don’t just come in 55 gallon drums or are tremendously expensive. This weekend I think I can boil this info down and send it to you. I looked at quite a few web pages, technical histories, forums, etc.
