Frequently Asked Questions

AI
Martens are attracted to the warmth and scent of engine oils. Using bitter-tasting repellent sprays, installing physical cable guards, or fitting ultrasonic deterrents are effective methods to keep them away from your engine bay.
Most dedicated engine cleaners are safe for plastics, rubber, and metal. However, always avoid direct contact with sensitive electrical components and ensure the engine is cool before application. Rinse thoroughly if the product instructions require it.
For thermal and acoustic insulation, use high-performance heat shield mats or sound deadening materials designed for high temperatures. These mats help reduce cabin noise and protect nearby components from excessive heat transfer.
