3M Rodent Repellent Coating, 250 g| Rat Protection for Engine Parts and Wires | Long-Lasting Effect, Liquid

Works well and easy to use but make sure not to apply this rat spray on any painted surface of the car as it leaves marks which do not go easily

I tried the 3M Rodent Repellent Coating mainly for car wiring protection. The application is straightforward. the spray spreads evenly and dries into a thin, clear layer without leaving sticky residue. It’s designed to discourage rats from chewing cables, and in my experience it did reduce gnawing marks for a couple of months. The 250g pack is enough for multiple applications on a bike or small car engine bay.However, it’s not foolproof. In areas with heavy rodent activity, I still noticed occasional damage, meaning reapplication is needed more often than expected. The smell is strong during application, so it’s best to use in a ventilated space. Also, it’s a preventive measure, not a cure. you’ll still need to keep the area clean and free of food sources.Pros:• Easy spray application; dries clear• Helps protect wires; reduces gnawing• Compact 250g pack; sufficient for small vehiclesCons:• Not 100% effective in heavy infestations• Needs reapplication for lasting effect• Strong odor during use; requires ventilationBottom line: A useful extra layer of protection for car and bike wiring, but best combined with other rodent-control measures for reliable results.

good

Completely Ineffective in My ExperienceI applied at least three coats of this rat repellent directly to my car’s engine cover. Even after that, I found rat droppings on the very same surface where I had sprayed it. The attached photo shows the condition after those three coats.For a branded product, this was extremely disappointing. Despite multiple applications, it failed to keep rats away in my experience. A complete waste of money—I would not recommend it.

⭐⭐⭐⭐⭐A very useful product for protecting the car from rats and rodents. The spray is easy to use and has a strong smell that helps keep rats away from the engine area. It’s convenient to apply and doesn’t take much time. After using it regularly, I feel more confident about protecting the car from rat damage.Overall, a useful and affordable product for car owners. Recommended, especially if you frequently park your car in areas where rats are common.
