In the video he uses a wire brush on a drill, what type of grit would you recommend? Do you think this is a good idea to remove rust in this fashion?

Main question is are there ANY PARTS you should NOT spray AT ALL? This guy seems to spray just about everything.

What are your experiences in this area? What have you done think works doesn't?
As always any feedback is appreciated! ::grin::::grin::

Hey frontiermane03, did you notice that he didnt actually remove the rust. He just knocked off the crusty top layer. I live in the rust belt and can tell you from experience that "rust never sleeps". I plan on cleaning and undercoating my truck, but after knocking off the loose rust I will apply a product called corroseal which is a rust converter primer. It actually causes a chemical reaction when applied to rust that turns it in to a hard black coating that can be painted or rustproofed over. This stuff goes on as a milky white color and after it dries it turns black. I used it years ago on my 79 ramcharger, and also on my Harley. I never bothered to paint over it because the black looked pretty good on its own. I ordered a 32oz bottle through h depot for under 25 bucks. If you dab a little bit at a time, it goes a long way. You might want to look in to something like this before encasing your rust in undercoat.

"Ospho" (Phosphoric Acid) It's cheap and readily available at hardware stores.
Turns rust black, but needs to be followed up by a sealant coating

Thank you plan B, I am all about a cheaper alternative. That would be perfect to do my frame and axle, cause I will be painting to clean that up. Most of my rust is just surface rust from a few years in buffalo NY, after spending most of its life in Florida. I am not planning on driving my 01 2wd during winter. Unfortunately during our winters they use salt and for about 4 or 5 months during the winter, and every day when you drive, your car gets a salt bath. I will probably pick up an older caravan (06 or 07) for my winter ride, cause they are bears in the snow. I used to have a 2000 caravan with a 2.4 4cyl front wheel drive in it, and I drove it for 10 years and 300,000 miles and never got stuck in the snow (and we get a lot of snow), but it rusted bad and I had to put it out of its misery.

after you get it to turn to a hard black surface what type of products are best to paint/seal with?

I just plan on using spray paint on the frame, torsion bars, bumper mounts and radiator support and undercoat on most everything else.
