Removing Undercoating? Just curious if anyone had done this lovely job & knew the best way. Not very excited about laying on my creeper for 2 weeks heating the entire bottom of the new car in 6" squares & scraping the $hit off with a putty knife. 
I've read a "needle gun" works pretty good. (a small air hammer device with a bunch of needles sticking out....kinda looks like a squid) But I don't want to buy one if they don't work. Any guidance would be aprreciated!

The needle gun will only make a nice new pattern without removing a thing.

When I changed the fuel filter on my old 99 it had undercoating and as soon as the fuel hit it it pretty much melted off in that area... granted it hardened right up a few minutes later on the drip pan and my arm... I agree with Don though stick with heat and putty knife.

Also if you use a needle gun, be prepared to not be able to hear for a few weeks. I have used one of those things more times than I can count...

That's gonna suck no matter how you do it.
Instead of a torch i'd suggest a heatgun.
As always if you want some help you know where I am.
I think 1 person heating and the other running the knife it might just go rather quick.

Sounds like something I did when I was 18. My first car was a 72 Chevelle. A southern car, (in New England southern cars are worth a lot more money. No winter means no salt on the road which eats cars off their frames within 10 years of being new in NE) so I wanted to protect it. It has rust proofing on the underside but I was particulary concerend about the floor boards which were perfect. So one day I took the interior completely out and coated it with the only thing I could find in our garage that I knew woud inhibit rust.
Roofing tar! I had some shoe sole material from where my dad worked (USMC-United Shoe Machinery) and put it over the top of it. Car stunk for a few days but then the smell was gone. When I sold the car the new owner had some choice words about it when he discovered it while restoring it. I thought I did a good thing.

And I picked up a new 950* heat gun with nozzles for under $30 shipped on Ebay. I'm stoked about this project...
