FAQ's for Rhino Linings & New Hampshire Oil Undercoatings

What is so special about New Hampshire Oil Undercoating?


NHOU is a fluid (jelly like), drip-resistant, solvent-free, non-toxic, super lubricating metal conditioner infused with "active" rust inhibitors that creeps and penetrates – all in one formula! It is not a sealant that traps moisture, nor is it messy and drippy. Its active rust inhibitors last up to 12 months. Available in clear so you can actually see it preserving the original “factory new” appearance. Or choose our popular "Back-N-Black" that offers the same protection but will substantially improve the appearance of a rusty undercarriage. It will not dry out, chip or peel off and its lubricating benefits continue indefinitely. This product was developed by people who know the business (New Hampshire Chemists). It is specifically designed for automobile undercarriage protection. Oil-based rustproofing is the most effective way to treat rust and corrosion. Our oil is formulated to displace moisture and deprive the surface of oxygen. When you take either out of the equation, oxidation cannot occur, so as long as product is present rust is held at bay. NHOU is formulated to migrate and creep. This is especially important in the hard to reach areas of a vehicle (rocker panels, door panels, cab corners, cross members) that are prone to rust.




What time time should I drop off and expect to pick up my vehicle?


We recommend to drop off your vehicle when we open in the morning at 8:30 am. I will give you a call once the job is complete for you to make your way back to the shop which will be before we close at 4:00 pm. We complete almost all our jobs the same day, except for large projects. If you choose to wait for your New Hampshire Oil Undercoating we can schedule you a time slot to arrive by and the application will be finished within 1.5 hours.




Will it void my warranty?


Absolutely not! NHOU prevents rust and makes the vehicle work better and last longer. While the manufacturers probably won’t admit it, they just have to love NHOU because it will reduce the number of corrosion related warranty claims they are obligated to pay. New Hampshire Oil Undercoating is non-conductive. We work with many new car dealerships and they send us their vehicles to get protected against rust.




How much does it cost?


I recommend visiting the "Cost" link on this website or call me directly. Typically though the New Hampshire Oil Undercoating starts at $275. There can be a slight upcharge for extra rusty or dirty vehicles to allow for more prep time. The Rhino Lining chemical that we offer: "Hybrid Polyurea" is very durable, sprayed on hot for a attractive fine grain look & is a great value.




Do you clean the car first?


We perform a dry cleaning using compressed air and metal spades. Our goal is to remove dirt, heavy scale and loose failing factory coatings. If your vehicle has excessive mud due to off roading we recommend you have your undercarriage washed at a car wash 48 hours prior to your NHOU appointment.




Can it still be applied in the rain?


New Hampshire Oil Undercoating - "No". If it is going to rain the day of your scheduled appointment, we should reschedule or arrange to drop off your truck to us in advance to keep the undercarriage dry. Rhino Linings - "Yes". Rain does not effect the application of a Rhino Lining.




How soon can I wash my car?


You can wash your vehicle immediately after the treatment. Unlike other preventing methods, it will not trap moisture. It literally pushes it away, leaving behind a corrosion fighting lubricating film. We "DO NOT" recommend undercarriage washes as this can reduce the life expectancy of the product. Even in the winter with road salt on your NHOU we still DO NOT recomment undercarriage washes. NHOU is more powerful at preventing rust than the effects of water, oxygen and salt are at creating it. You can confidently drive in the winter without damaging your vehicle ever again!




How is it applied?


NHOU is sprayed with high pressure, airless, atomizing tips which pushes the product deep into the seams, cracks and crevices where corrosion starts. Once applied, the product removes the moisture in these areas and provides a strong adherence to these surfaces, remaining active with excellent “creeping” and self-healing abilities. We also use fogging guns to apply NHOU inside body cavities such as cab corners, rocker panels, inside the frame and bottoms of doors. Rhino Linings are sprayed on using a high pressure, heated, plural component machine that causes the chemicals to form a durable plastic coating in less than 10 seconds.




Where are you located?


We are located 2 miles south of the Bourne Bridge heading towards Falmouth on Rt 28 south. Keep a eye out for Martys Chevrolet, take your next immediate right onto Otis Park Drive. We are the 3rd building on left. Rhino Linings of Cape Cod 5 Otis Park Drive Bourne, MA 02532




How long does it last?


NHOU is recommended to be reapplied once per year if: - It's a daily driver, over 8k miles per year, driven in salty conditions or visits salt water boat ramps. - If the vehicle is secondary, and is not subjected to the conditions listed above then 1.5 - 2 years might be possible. - Do not, for any reason, wash the undercarriage of your vehicle once NHOU is applied. Make sure if you visit a car wash that they are NOT including a undercarriage rinse. This will severly reduce the life expectancy of the NHOU. Our product is more powerful than the effects of water, oxygen and salt combined! You will not rust so long as our product is in place, so please don't rinse it off. Rhino Linings last indefinately and carry a lifetime warranty.




How long does it take to apply?


The New Hampshire Oil Undercoating takes about 1.5 hours to apply. You are welcome to wait for it on our comfy couch with WiFi or drop it off and return later in the day. Our Rhino Linings take average 4 hours to apply, so we recommend dropping off your truck for the day.




What is your availabity?


Depending on the time of year and incentives from car manufactures we can book your appointment anytime from the next day up to 2 weeks in advance. Our busy season is the fall through mid-winter.




Is it too late to apply to a used vehicle?


In most cases Rhino Linings can still be applied so long as the metal isn't rotted. New Hampshire Oil Undercoating can be applied to rusty vehicles as it soaks into the surface and maintains a jelly-like consistancy that cannot peel off of the vehicle. However, if your vehicle has severe rust we recommend our Rustoration service to physically remove scale, convert the surface rust into zinc oxide using NHOU brand "rust converter" and then top coat with NHOU. Rustorations correct the damage, NHOU prevents rust from returning.
