Has anyone ever used the Eastwood undercoating remover? Is it any good/worth the price?

Hello,
No I have never used it before. Is it flamable? Must not be the more I think about it. Didn't go to Eastwood yet to read about it.
How much do you want to remove and is the car on a rotissierie?

Be careful getting the old undercoating on bare skin when you're all sweaty. There's something in it that can cause a sever, long-lasting rash once it's embedded in your pores. PCB's?
Had a buddy that looked like he was boiled in oil for about 6 months. I've gotten a patch or two from it, but it wasn't nearly as bad as my friend's reaction to it.

I'm guessing we are laughing because we all did that job on our backs at one time or another. God did that suck.

I removed all the undercoating, road tar and dirt from the bottem of my car in 3 1/2 hours with out even touching my car. Not one scratch or gouge mark anywhere. One afternoon and I was done. Used a steam pressure washer with a little gasoline in a sprayer to soften the tuff stuff. I've done it now on several cars and many trucks over the years. It's worth the trouble/cost to rent a steam pressure washer for this job, imo. I have been lucky to own several of these pressure washers that we use to maintain a small fleet of tanker trucks. before  after same afternoon.     I removed all the seam sealer from the inside of the car also with it.

The pressurized container that I sprayed the gas with to soften the tuff undercoating that didn't come off the first pass.  The pressure washer. I was able to stand up, breath no fumes or dust, no open flame, no gouge marks, no skinned up hands and it was done in just few hours. Now standing there with 1500 PSI ,4+gpm at 200 degree temp point blank for 3-4 hours is not real easy, but the job was done in one afternoon and only had to clean up once. And the less than 2 gallons of gas I used evaporated before it got to my grass, so it didn't cause any enviromental issues. I swept up the heavy undercoating off the driveway with a shovel and used my pressure washer to clean my driveway. 3 times now at home and still have a real nice yard with grass. Oh yea,I used it to remove the repaint on the car that I'm drilling out the spot welds so I can see better before drilling in the picture below.  Here's the doors on my gold 71,  Used the same pressure washer to remove all paint from them. It'll remove any repaint leaving the original paint pretty much intack.    Did a hell of job on these fenders.  Bottem of my 71 before blasting and repaint after undercoating removal.

You can also use one of those oscillating tools with the scraper blade. They make it pretty easy for getting the bulk of it off.

I wanted the undercoating removed from under my 55 Chevy BelAir. I have a Media Blasting setup and used Baking Soda to remove a 12" square area in a half hour, it just seemed to 'melt' and roll the stuff up like gum. I opened a bag of Grit-O-Cob, ground corncob. I ended up with the same results as what Challenger1 ended up in about the same amount of time (3-4 hours). But his process would be an easier and cheaper one for just anyone to do. My process worked great for me because I have the blaster, compressor, and access to cob, whereas I would have had to go out and rent a steamcleaner. Just more options to throw out there.
Many ways to do it. 
I like pressure washing first before media blasting because it allows me a very light media blast to get the metal bare and I'm not blasting grease and oil into the metal. I use less media too which makes cleanup easier.
I have been media blasting for like 25 years.

I've seen pics of it pressure washed that you posted before, my question is: how much did the equipment needed to do this cost? It does clean it very nice. I always went with a propane torch and scraper. Another issue is I have yet to scrape one that was that clean. I always have cars that have parts that had flaked off and rust... so I had to blast them after anyways and I would blast them anyways to have a good start for epoxy and needed body work.
