Hey friends, this is basically on the entire undercarriage as well as in the wheel wells, I assume this is something from the factory? Any good ways or tricks to remove all this?

Soak it in anything? A putty knife works, but it takes up a lot of dust and is very difficult. There’s gotta be some sort of remover for this.
 
I had the best luck taking that stuff off when it is a bit cold actually, like below freezing. You skim it with an air chisel and it comes off in huge chunks.
 
I have used a Harbor Freight needle scaler on 5 cars so far. Works good, but make sure you have a good set of ear plugs.

I was working on my sound deafening, heat, defense, rubber junk that was on my floor last year when it was like -5° outside and because it was so cold, it came off in one chunk as opposed to being tar. I was wondering if this was a little bit of the same situation
 
I have various width scrapers and a propane torch......I keep the scrapers sharp, and round the corners so they don't dig in....... I have a wide one with a nice radius for inside the wheel wells.........goes pretty fast

I took mine off with a small propane torch and a 1-1/2" scraper. Sprayed the underside of the car down with Gunk
Foamy Engine Degreaser and let it sit overnight. Next day I pressure washed it all down. Squeeky clean.

If you just want to remove the old factory undercoating, and replace it with basically the same, RUSFRE works pretty good for the new undercoating. I scrapped my Dart with a propane torch. Then sprayed with RUSFRE. If you are redoing the bottom of the car for paint, ZYZZYX' s method looks like it worked well. The undercoating is just tar, so petroleum based thinners will dispurse it.
RUSFRE available at bodyshop supply stores. Can be sprayed with proper gun, paint brush or roller. Can be thinned 10-15%.
