ITW Brands: Rain-X, Gumout & Black Magic

 In Automotive Product, Product Testing

A few weeks ago I was invited to tour the ITW (Illinois Tools Works) Brands headquarters here in Houston Texas where the Research & Development department for Rain-X, Gumout & Black Magic Car Care is located. They have owned the brands for the past 8 years after acquiring them from Shell Oil Company. I was already familiar with Rain-X products and have used them in the past along with Black Magic Care but this was a great opportunity to get reintroduced to these popular automotive brands and to learn more about the process.

We start off with Black Magic Tire, said to be the best product on the market for tires because of its spray ability and chemistry, which makes the product extremely stable and consistent. It is Streak Free with a precise and consistent spray pattern that offers a high shine. The creation of this product was more of an art than a science and they have multiple patents that were granted 5 years ago for the formula and leveling agent.

The chemistry of this spray has to be right to make this solution and they worked very carefully on the formula. This product is homogenous, so it is always stable regardless of where you store it and you don’t have to worry about it expiring. It has a high and long-lasting shine that lasts for weeks that no one can compete with. Being silicone-based it makes for good consistency & longevity and when it rains it helps make it more uniform compared to the water-based formulas out there which would just completely wash out. Unnamed competitors have a messier spray pattern that does not deliver the same product and dispenses wasted material.


We then move onto Gumout Fuel Cleaner which is a product you pour into the gas tank before you fuel up your tank. It contains PEA chemistry consisting of Ether and Nitrogen molecules and is one of the best gasoline cleanup products on the market. It travels through the fuel system to attack the injectors first where if dirty restricts the fuel flow in the combustion chambers. It then moves into the intake valves and lastly the combustion chamber which has the hardest despots to clean. The thickness of the dirt reduces each time you use this product before filling up and works on all carbureted and new engines. Compared to competitors Gumout All In One has the most additive, the best detergent and molecules in a single bottle. After just one tank you will feel a difference but it is recommended to use this product with 5 tank refuels.

Rain-X itself has been around since 1972 and started as a glass water repellent which is a product that helps with your driving visibility in wet conditions and was first developed for the aviation industry. It is the #1 brand in wipers, glass cleaner, and glass repellent. I was introduced to the newest Rain-X product Waterless Car Wash which is a convenient product to have if you have no water or bucket. It cleans, shines and protects with its hydrophobic formula that provides a water beading effect. The beading means the surface is protected, difficult for dirt to stay on and easier to rinse clean during washes. Comparing to similar products on the market this goes one step further with surface protection.

The Rain-X Silicone AdvantEdge Wiper Blades are designed to be durable and long-lasting while consistently performing in a variety of temperatures and environmental conditions. From the icy cold winters in the north to the year-round blazing heat of the south, the next step in the innovation process was to develop a wiper blade that met these specifications.  Also, Rain-X also carries a Premium Headlight Restoration Kit that restores aging headlight clarity. It uses dual mechanical and chemical solutions of sanding and refining to remove scratches and impurities. It polishes and protects to optimize clarity and prolong results.
