penetrant
Looking for the best bolt penetrants to use. and best methods you have found for removing old bolts. Want to strip Nd break as few as possible. I hear WD40 isn't the best choice.

Hmm...looks promising. I'd never heard of Kroil before. Good suggestion.

No matter what you use, always spray and let it soak for a day or so, and several applications is always preferred.

Seafoam Deep Creep
Best I have ever used ...no comparison even to Kroil which is a great product.
Seafoam makes great products
PB smells exactly like liquid Wrench which both work good as well

Sili Kroil is the best by far. I have a can out in the shed if you want I can email you their address. I just removed my motor last weekend. The exhaust manifold bolts were all rusted and nasty looking. I sprayed them with Sili kroil for 3 days in a row and then on the 4th day I tried to remove the bolts again, they came right off.

I don't know if this is a good price, but here's a Kroil link:

Orscheln carries the Seafoam engine/fuel system cleaner (the best stuff out there), they might have the deep creep. I just use PB blaster and heat. Nothing like the smell of burning PB blaster in the morning...

But you have to ask the question: How do they work. On an exhaust manifold bolt for example. You spray them on but how does the fluid work its way into the inner threads of the bolt. Those bolts are seized on solid. Just spraying the outside does not seem to make much sense.

That's why they call it penetrating oil. It's an oil, with rust breaking chemistry. It's an oil, so it seeps into tiny holes and pits, slowly eating away the rust and crap. It won't work immediately, but after a few days of being soaked, the oil make it through enough of the rust to allow you to break it loose. Once it's broken, it comes with little effort.

Kroil or Sili Kroil is by far the best you can buy
This is the manufacturer: www.kanolabs.com
From their website:
Try any Kano product with no risk to you. If it ever fails to meet your expectations we will immediately cancel the charge. It costs you nothing! ------ There is no risk to you! ------
wow, I wonder if they know about our trailing arms.....

There are occasions where a bolt is so rusted that no penetrating oil will free it up, but I have had good success with PB Blaster. You have to have a lot of patience when working with 30+ year old fasteners. I've heard that Kroil is better than PB but it isn't as readily available so I haven't tried it. The Seafoam product sounds interesting - if I can find some localy I'll give it a try.

If you have a Napa, Oreilly, or Advance, call them and see if they can order it. Then just stop by and pick it up. Nuff said.
