Frequently Asked Questions

How does Roadkill Expert differ from Roadkill Ultimate?

Roadkill Expert is a two-layer product — butyl damping layer plus aluminium top. Roadkill Ultimate is a three-layer product that adds an acoustic foam layer on top of the aluminium, combining vibration damping, heat dissipation, and high-frequency sound absorption in one sheet. Expert is the cost-effective bulk option; Ultimate is the premium single-application solution where maximum performance per sheet is needed.

How do I apply Roadkill Expert?

Clean the metal surface with wax and grease remover or methylated spirits and allow it to dry fully. Cut the sheet to shape, peel the backing, press it firmly onto the panel, and roll with the Stinger RKINSTALL roller to ensure full contact and maximum adhesion.

Is 36 sq ft enough for a full interior treatment?

36 sq ft is sufficient for both front door inner skins and a boot floor, or the floor area of a small to medium vehicle. For a comprehensive full-interior treatment including doors, floor, and roof, additional packs are recommended. Contact the F.A.E. team for guidance based on your specific vehicle.

Can Roadkill Expert be applied to a vehicle firewall?

Yes. The firewall is one of the most effective application points for Roadkill Expert — it reduces heat transfer from the engine bay and exhaust, as well as engine vibration transmitted into the cabin.

Is Roadkill Expert safe to install in an enclosed vehicle cabin?

Yes. Roadkill Expert is odourless and non-toxic, with no off-gassing or unpleasant smells after installation — safe for the vehicle cabin immediately after application.
