Re: rust penetrants
I wonder how they kept all the of rusted fasteners at the same torque value as far as being stuck. I have taken 16 track frame bolts out of a crawler, and everyone has a different amount of torque necessary to remove them.

Re: rust penetrants
Hi,
Yes, it would be nigh impossible to have rusted / corroded fasteners all have the same amount of resistance to loosening. No matter what the thing is. I would think that track bolts come as close as one could to having a bunch of them all in the same state. And, they wind up all over the place as noted.
I can say that of the stuff listed, ATF+Acetone works the best. There used to be a product from now-long-gone Kendall that was really good: CML260. We used that in the old family business equipment dealerships. Some of the racing crowd loves something that Dodge sells. I have a can somewhere, and I'll post what they call it when I find it.

Re: rust penetrants
aint concerned with the test....its the end result...showing the weasel piss...by far to be the best release agent. tho surprises me that wd40 shows up better than pb blaster and liquid wrench better yet.
suspect test accomplished with new torqued bolts in some fashion?

Re: rust penetrants
Yeah, WD40 would be the last product I would grab for a penetrant.

Re: rust penetrants
A very good water dispersant. The WD people have a WD Specialist version that is much better than the OG.
Re: rust penetrants
I'm a huge fan of the kroil, plus is smells so look good. As far as the test it doesnt say anything about rust. My guess they were testing the same fastener with differnt lubricants.

Re: rust penetrants
It appears this info may have come from the April 2007 "Machinist's Workshop" magazine. Apparently you need to find a copy of the magazine to see how the actual test was done, fasteners rusted, etc. I did find info saying there was an artificial rusting method (but not what the method was) and three bolt/nuts (no sizes or types of finish used) tested for each product. It also appears the penetrant was applied and set for 8 hours before the fasteners were tried. Some general consensus on web discussions is: How could it be confirmed the fasteners be rusted to an equal amount, sampling quantity was too small, something is better than nothing, and different people think the product they use works best. This is a subject, like oil, that can generate pages of discussion, and bring out some ideas.
Re: rust penetrants
It kind of seems to me that what most of the rest of the world thinks is a rusty part, any of us on here would be ecstatic to have the little amount of rust on our stuff. I have had some crawler come in that the deluxe seat has holes rusted in it, the track pad bolts did not even look like hex heads any more, and you couldn't budge any track frame bolt without breaking it off. I think it takes years to really "rust" a bolt into a spot that it doesn't have any intention of coming out of.
I would guess anything that operates in salt water would be about the same thing.
