Frequently Asked Questions

Woolwax® is a lanolin based, solvent free, non-hazardous, corrosion preventative designed for use on any known metal. Woolwax is blended with other proprietary agents to provide long term protection against salt, liquid calcium chloride, brine, and all other ice control agents that are being used by municipal departments.

Commonly referred to as an "oil-based undercoating," Woolwax was intentionally formulated  to be thicker than any other lanolin based product on the market. As a result,  it is FAR more resistant to road-wash and leaves a grease-like, SELF-HEALING film, that is DRIP FREE.  Woolwax® will NEVER DRY and CREEPS 4"- 6" in every direction allowing it to deeply penetrate into metal cavities to provide superior corrosion protection and lubrication. 

Woolwax® should be applied annually or bi-annually. Application frequency heavily depends on the conditions your vehicle will drive through and the distance you drive every calendar year. Woolwax® is applied to the vehicle undercarriage, frame rails, rocker panels, doors, inner body panel cavities, battery posts, brake lines ,hoods, and more! This product is not a rust remover or converter.. however, it can be applied over existing surface rust. 

Woolwax® forms a heavy hydrophobic barrier which prevents moisture and oxygen from reaching  existing rust, thereby halting further progression. 

 In short, Woolwax® lasts much longer than any other  lanolin based products on the market and has proven to be an exceptional vehicle undercoating product.

Three environmental factors must be present for rusting to occur: iron, water, and oxygen. Rust forms when these three elements combine and create an exothermic reaction. Iron + water + oxygen → hydrated iron(III) oxide (rust).

Woolwax® creates a hydrophobic film barrier which blocks moisture and oxygen and encapsulates existing rust. Without oxygen and moisture rust cannot progress. 

• • Hard coatings are expensive and require extensive preparation time

  • In order for hard coatings to be effective they must be applied to a 100% rust free, clean, dry surface .. this means any corrosion that is covered with a  hard coating will continue to decay and eventually create a void under the "protected" surface for water and air to enter.

  • Rubberized coatings are notorious for bubbling out trapping  water and air and accelerating the rusting process .

  • Rubberized/hard coatings interfere with mechanical maintenance by encapsulating nuts, bolts,  electrical connections, etc. This requires removal of the coating before any tools can properly access contact points. Additionally, these coatings can  bond electrical connections together making  difficult connectors even harder to break loose and identify.

  • Rubberized/ hard coatings WILL NOT PENETRATE OR CREEP inside internal cavities. These coatings cannot be applied  inside of body panels and  frame rails in such a way that will guarantee complete coverage. This allows  salt and other corrosives to attack your vehicle from the inside out. Overtime these coatings will dry, chip, flake, and peel..  causing additional necessary repairs and  financial burden.

Woolwax® is Non-Drying/ Self Healing/ Non-toxic 

Alleviating all the shortcomings of hard/rubberized undercoatings mentioned above and more!

• It NEVER dries and Self heals!  You will never have to worry about scratches, scrapes, and rock chips again because the creeping protection of Woolwax will always keep every nook and cranny covered,  regardless of preexisting rust conditions. It has the ability to "FOG"  internal cavities resulting in 100% coverage of those impossible to see and reach areas. Woolwax® will seep into nut and bolt threads and  other delicate problem areas such as brake lines ,body mounts, and structural items keeping them lubricated and free of corrosion. Woolwax® is also non-conductive and will not bond electrical connections. Being a non-drying coating means that Woolwax® WILL NOT bubble, chip, crack, or peel, and cannot be undermined from an inside cavity or exterior surface.

• Woolwax® costs less than half of hard/rubberized coatings and requires almost no prep time. Most cars/trucks can be completed within 60-90 minutes if the vehicle is brought in reasonably clean and dry condition.

• Unlike hard/rubberized coatings Woolwax® can be applied over any existing rust surface and will prevent rust from progressing further on contact. Loose/ bubbling or cracking rust scale should be removed prior to application. Needle scaling, power washing, and compressed air removal will suffice to remove excess rust. Yes, in a perfect world it would be better to remove all the rust to bare metal however, without completely stripping the frame with acid or sandblasting there is virtually no way to eliminate 100% of the rust on your vehicle, especially in those inaccessible areas inside frame rails and cavities.  For the typical vehicle with or without existing rust build up Woolwax® is by far the most cost effective option in the undercoating industry.

• Woolwax® is Non-toxic and 100% solvent free 

• The only tradeoff with Woolwax® is that its not a permanent product. While it can take a beating and will hold up for years Woolwax® will need an occasional touch up to maintain its strength. Most customers can get a full application done the first 2 years and  only need to come in for touch ups every other year afterwards. This is a small sacrifice considering the high level of protection your vehicle will have compared to other coatings.

Woolwax® will not affect paint, plastics, or undercarriage rubbers negatively whatsoever.  Almost all rubber products located under a vehicle are oil and heat resistant to some degree. Rubber products do however have a limited lifespan before they begin to get brittle and crack. 

Some people have had concerns that lanolin can cause damage to these rubber components but in all cases we have seen as an undercoating community Woolwax® was not the culprit. These components were failing due to age and environmental abuse. 

We have heard of some rubber weather strips around the bottom of door frames swelling when exposed to lanolin products. These are a type of open-cell sponge rubber and they are NOT oil resistant. To combat this issue, a light film of silicone is applied to the weather stripping before applying Woolwax® inside or around the lower portion of doors. 

1. Driving habits and environments can vary greatly, that being said we generally recommend an annual application to cover all the bases. Customers that drive less often or in milder conditions can often skip a year while others should get an annual touch up. We look forward to discussing a protection plan that is both budget friendly and tailored to your individual needs. Getting your vehicle undercoated annually is an important investment that will greatly extend the life of your vehicle and save you money in the long term. 

2. We undercoat vehicles in all seasons and weather conditions however, the BEST time of year is during the warmer months of spring and summer. The heat will allow Woolwax® to creep deeper into cavities. Furthermore, these months generally keep vehicles cleaner and dryer allowing for fast turn around times. You will also have the peace of mind knowing that your vehicle has been freshly coated before the first snow falls and the salt starts flying.  Please be aware in the winter and or heavy rains we ask to keep the vehicle overnight to wash and dry/inspect the vehicle for the most effective application. 

1. Woolwax® comes in 2 color combinations straw (clear) and black. Clear will darken metal and rust stains and a lot of times make the frame components appear black. Woolwax® black is a great option if you are looking to conceal  rust/imperfections and get a cleaner look. The black coloring will not fade or wash off but is more expensive because more product will have to be used to ensure no color gaps and extra prep is needed.

2. Woolwax® will never completely wash off when exposed to road wash under normal driving conditions because of its thick formulation and creeping ability. Most times areas that appear to have washed off completely still have a thin grease  layer protecting the metal. However, it is recommended to avoid undercarriage car washes especially during the winter months because the mix of detergents, high pressure spray, and salt chemicals will weaken the coating overtime. 

3. No, at first there might be a mild lanolin odor while the coating is still fresh but after a few days  the oils have time to seep into the metal and the smell will be completely gone. Woolwax® is treated with a proprietary process that neutralizes odor, while other lanolin products are not. Woolwax® is solvent free as well so it does not emit any chemical odors.  

In short, yes! Many undercoaters are finding that even the newest aluminum body vehicles available today are corroding. It is still recommended to get the same undercoat treatment as any non-aluminum body vehicle. Aluminum body vehicles are built with steel frames and hardware. Many important items like brake lines and body mounts are highly susceptible to rust and corrosion as well.
