Depending on how sloppy and oily it is... a hair dryer and a semi rigid plastic scraper.
I'd avoid the heat gun (too hot) unless it's really dry, brittle stuff. Same with a metal scraper, it will tend to dig in and scratch the sheetmetal.

Follow up with mineral spirits on a rag.
Other solvents (lacquer or enamel thinner, etc.) flash off too quickly and are very flammable.

I recently finished my entire under carriage....

My process was to use a wood chisel that I had put on a grinder to dull the edge so that it would not dig in to metal. I used this because it was heavier than other tools and so it would cut through the junk easier.

Next, I used a soft wire brush on my drill to get the remaining junk off. I was careful not to remove the paint by not pressing too hard or using too stiff of a wire wheel. If the area to be cleaned was wet then I would first wipe down with mineral spirits or lacquer thinner, let dry and then wire wheel.

When all this was complete, I wiped the entire area down with lacquer thinner before painting.

I used a harbor freight scraper tool with flexible blade for the softer tar stuff and GUNK for the hard stuff. Spray it on for a day and it comes off real easy.

A metal blade putty knife, or 5-6" drywall knife will work great as well

Easy off oven cleaner. Sprayed on,1hr later wiped off with a rag. The rest of the car I used plastic scraper,#2 Black&Decker cone wire wheel and a 3M medium sanding disc on my die grinder. I didn't strip all of it to bear metal. It didn't seem necessary to me. I removed just the under coating.

+1 on the gasoline. I did my entire undercarriage with gasoline and a rag. Just be careful and do it in a well-ventilated area and you'll be fine.
