Scrape the undercoating away with a small paint scraper. As you warm up the undercoating, use a small or medium-sized paint scraper to remove the undercoating. Hold the paint scraper directly against the undercoating, and push it forward with moderate pressure.
Use a wire wheel for the most efficient removal method, try an air scraper for an easy option, or use a heat gun and scraper for a hands-on method. Removing the undercoating is a time-consuming, tedious job, but with some patience and elbow grease, you can remove the undercoating from your vehicle.
Rust-Oleum undercoatings are permanent and cannot be removed. If you have a drip or splatter to clean up, remove quickly with acetone, mineral spirits or xylene.
Acetone will eat up latex paint, but not oil (unless it's a thin coat). "Goof Off" may work too.14 may 2009

Undercoating your vehicle protects it from corrosion and rust. If you need to remove the existing undercoating, you have several options. Use a wire wheel for the most efficient removal method, try an air scraper for an easy option, or use a heat gun and scraper for a hands-on method.
If you want to strip the existing undercoating off, get some paint stripper, apply it with a brush, wait about 30 minutes and peel it off with a putty knife, or scraper. Get the cracks and crevices with a wire wheel, then neutralize the area and prep for paint.9 jun 2006
For more stubborn stuff, apply heat from hot air gun (not so much as to scrorch as you have done) but just enough to warm and loosen, then scrape off. Finally, to remove the residue, brush on some parrafin, leave to soak in for a few mins and the underseal remains will just wipe off onto a rag.16 feb 2010
Strip elastomeric paint with a chemical remover. You can choose among several types to brush on and dissolve the elastomeric coating. Once you dissolve the coating, you can pressure wash it off or peel it away.
