Would this product be safe and effective for removing rust from a blued firearm?

It will not harm your blued finish. You would not believe how well this works, it is just amazing. I used it on firearms with a little bit of rust and cleans things right up with no issues. I also like to plug The end of the barrel filled with Kroil and let it sit overnight 24 hours. I do this after a thorough cleaning of my fire arm and barrel that looks like his perfectly clean. 24 hours after I've soaked the Kroil in the barrel you would not believe the amount of blacks soot/junk that came out after the soaking. Also I have used it on squeaky doors, the door on my Dodge Ram starting to squeak, one application no squeak whatsoever. I swear this stuff must be waterproof. Even going to use it on my shot on my truck when I replace my shocks to help loosen the bolts. You will definitely not be disappointed. Definitely buy it, but it, but it.

I have a bolt that goes through a 5" collar. The bolt and the collar are fused together by rust. Will this product penetrate through the whole 5"?

That's pretty much a see what happens. To my knowledge this is the best penetrating oil available anywhere. Give it a try. I would give it about 5 to 10 applications, with a minute or two in between then give it a try. Give it time to work thru. Good luck.

What is the difference between the Kroil penetrating oil and the lube???? I plan on using either for gun maintenance, which is better??

Use both Kano and a premium gun lube. The Kroil should be used for rust removal and bore maintenance - its amazing how much stuff Kroil will remove from a "clean" bore. It is not an ideal operating lube, being too thin to persevere. It was designed as a cutting and penetrating oil. Really great stuff for lubing drill bits during cutting. Use premium lubes on action friction surfaces. Anything from Microlon, Break Free, or probably a dozen other manufacturers.

Is this product a good choice for removing rust from a table saw surface? This is a heavy cast iron/steel top surface on a Delta saw.

No. Not because it won't work but because it won't work any better than other products that are 1/3 the price. I wouldn't use penatrant for rust removal. Either wd40 and steel wool or evaporust or naval jelly.....depending on how bad the rust is
