Pacer S77 Sound Deadener 1L

Pacer is an Australian brand of automotive and industrial maintenance chemicals, producing corrosion inhibitors, rust treatments, cavity wax, and sound deadening products for vehicle and equipment protection. Their S-series products are designed for use in the automotive trade and by maintenance professionals requiring reliable, long-lasting corrosion protection and noise reduction on steel and metal substrates.

Pacer S77 Sound Deadener is a bitumen-based aerosol coating applied to vehicle underbodies, wheel arches, and floor pans to reduce road noise transmission into the cabin and to provide a secondary layer of protection against stone chips, moisture, and corrosion. The aerosol format allows application to complex profiles and recesses without specialist spray equipment.

Where this product is used

Sound deadener and underbody coatings are used in vehicle body and noise reduction applications:

• Automotive restoration and repair where underbody protection and noise reduction are required after panel or chassis work.
• New vehicle preparation where additional sound deadening is applied to wheel arches and floor pans to reduce cabin noise.
• Trailer and utility body construction where underbody coating provides corrosion protection on bare steel floors and cross-members.

Selecting the right option

S77 Sound Deadener is applied to clean, dry steel surfaces — remove rust, scale, and loose coatings before application for best adhesion. Apply in multiple coats for maximum sound deadening effect, allowing each coat to skin over before recoating. The aerosol is suited to wheel arches and complex profiles; brush-apply bitumen products are available where larger flat areas require coverage beyond the aerosol's practical range.
