Various tools and techniques for removing undercoating from the bottom of a car.
 
  
==Miscellaneous tips==
 
*A [[Automobile body and frame rotisserie|rotisserie]] can be very helpful. Removing undercoat while sitting on a stool is much easier than crawling under a vehicle.

==Removal methods==
 
Remove chunks first, then use solvent for the remainder.
 
 
===Using heat===
 
Heat gun, or propane torch. Apply carefully, only a small amount of heat should be necessary.
 
 
===Mechanical removal===
 
*Putty knives of various sizes.
 
*Needlegun scaler. It may leave pock marks on the metal, and works best on rock-hard undercoating.
 
*Steel wire brush on a grinder.
 
*Drill-mounted brushes.
 
*Hit it lightly with a hammer or air hammer. Try using a wood chisel.
