3M Undercoating protects vulnerable automotive metal parts from corrosion and abrasion. Specifically designed for automotive undercarriages, wheel wells and body panels — quarter panels, under hoods, trunks, undersides of floor pans — it's equally effective in many other automotive applications. Multi-purpose aerosol undercoating is available in a rubberized formula that can be painted.

Key features:

• Provides a tough barrier and protects metal from road debris
  
• An aerosol undercoating with smooth texture in two forms, paintable and non-paintable
  
• Multi-purpose undercoating may be applied to cars, trucks and recreational vehicles
  
• Hides welding marks and other repairs
  
• Sound dampening properties help reduce road noise
