3M Rodent Repellent Coating Spray, Prevents Rat Bites in Engine Parts and Wires, Highly Effective, Leak-Free, Easy-to-Spray, Bitter Taste, No Kill-only Repels (80g, Pack of 1)

We have a big rat problem in our apartment complex and lot of cars have been affected. Just last week rats sneaked in my seltos hood and chewed off the ac wire. On suggestion of my local car workshop owner, I got this for my seltos. It seems to be effective, but it is too early to confirm the longevity of this. Some pointers: Get the engine bay area washed before applying this. This will leave a clear shiny layer on the areas where it is sprayed. Spray when the engine is cold. Use a 2nd layer spray after 1 or 2 days. Use 2 masks and sunglasses / eyeglasses when you spray this. The smell is very strong when you spray it and if there is wind, it can enter eyes and burn. Make sure you put some newspaper or cloth over the windscreen glass, as when I was spraying with bonnet open, some part of spray went to the glass and it formed small droplets which are rough to feel and very difficult to take off. I had a hard time to remove from front glass. Car shampoo didn't help. Finally I applied a little acetone on it and it seemed to work, but the acetone cleaning can damage glass or leave residue. So I applied them in small batches and asked my cleaner to wipe it off with colin glass spray immediately.

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 vehicles Cons: • Not 100% effective in heavy infestations • Needs reapplication for lasting effect • Strong odor during use; requires ventilation Bottom line: A useful extra layer of protection for car and bike wiring, but best combined with other rodent-control measures for reliable results.

Effective product for rat, product effective and long lasting it's effect to away the rat l. Easy to use.

Fancy spray, doesn’t really work after hours of application, either it’s not 3M or simply the product doesn’t put away rodents as it promises!

I purchased it seeing that its certified by NABL anf its sold through Amazon but the next day after using this spray for the first time i found the waste of Rat inside my car banet. Thought it would be old one, but after cleaning it and i sprayed all over the engine room and wheel arch and the next day also i found the waste in the engine room. I was totally disappointed and purchased the Tobacco leaf and placed it in the engine room a week before and till date i haven't found any waste after that. It just costed Rs20/- and it helped me but not the product which costs around 600/-.

Product is good. But this time received in little damaged condition.

Highly effective product! I have been using it for the last 6 months and am completely satisfied. I reapply it every 3 weeks, and there are absolutely no signs of rodents or their presence in the car anymore. It does exactly what it promises, and it's definitely worth the investment to protect your vehicle's wiring.

Product quality reasonable. Needs frequent spraying @ 6-7 days interval.
