The SDR is a SOUND DEADENING RUSTPROOFING treatment developed to reduce road-related noise while providing excellent rust protection to the underside of your vehicle. Unlike other undercoating products, SDR will stay pliable, therefore will not crack and will not allow moisture to form between the undercoating and the underbody.

The SDR has the following superior characteristics: superior resistance to abrasion and very good adhesion. It penetrates cracks, has no unpleasant odors and will not drip.
