tuf-kote 4941 Underbody Rust Proofing Wax Spray 500 ml Aerosol Anti‑Corrosion Underbody Protection for Cars SUVs Motorcycles Chassis Rust Prevention Wax Coating

One of the Best DIY product. 1. Get the car a pressure wash. 2. Spray the Diesel. 1.5 liters. 3. Wait for 30 mins 4. Shake the product well and start spraying. U need to shake it for every spray. For New WagonR only for all 4 wheel Arcs u require 2. If it is only a patch work 1 bottle is enough. For entire car underbody coating u require 4 bottles for single coat. However I don't recommend as u can't keep the can straight. At Rs.2500 u can get it coated by service center. This is best for Wheel Arcs. Also u can use it on Rusted Iron Plates. Gates, Grill doors but the colour is Black.

Bought 4 cans, but needed at least another two. I will do it again before monsoon starts. Good product. May be a bit more expensive.

Used it for the wheel arches where the previous rust proofing pealed off . The product is easy to apply and with a can you can coat 2 wheel arches of a small car . Please mask body panels to protect from overspray and clean the underbody and wheel arches before application .overall the product does a great job and can be done at home . The pictures where taken before the coat dried. I'll be uploading pictures of the dried wheel arches

Good

While the coating is smooth and waxy, coverage is very low. Will need 5-6 cans to cover whole of underbody in average car, more for big SUVs. That is excluding the mudguards -- one each at least ! How long it stands up to mud & sand blasts from the road, or from pressure washing, is to be seen. Used up 08 cans of this plus two of another brand for ladder frame small SUV (Maruti Gypsy) single coat, and still need more. Mudguard under side not done yet ! Works out more expensive than in a service station, where they charge for labour, too !

I applied to my car chassis where corrosion started but after two days it turns to black powder on surface.

Once the sealant is dry it is not greasy although the label says 'wax'. Easy to apply. DiY.

Product is good but quantity is less
