Bilt Hamber Atom Mac
Bilt Hamber Atom-Mac is a specialist corrosion inhibitor designed to protect vulnerable metal surfaces from rust after washing and exposure to water.
Key Benefits
- Corrosion Protection: Helps prevent flash rust and corrosion from developing on exposed metal surfaces after washing.
- Ideal for Brake Discs: Particularly useful for reducing the unsightly surface rust commonly seen on brake rotors after a vehicle wash.
- Highly Concentrated: Designed to be diluted with water, making a small amount of concentrate suitable for regular maintenance.
- Versatile Application: Suitable for brake discs, wheel hubs, suspension components, underbody areas, and other exposed metals.
- Easy Post-Wash Protection: Can be applied to wet surfaces following the final rinse as part of your regular detailing process.
How to Use
- Dilute Product: Mix Atom-Mac with water at approximately 2–5% concentration depending on the application.
- Complete Your Wash: Thoroughly clean and rinse the vehicle before application.
- Apply to Metal: Lightly mist the diluted solution over exposed metal surfaces such as brake discs, hubs, and suspension components.
- Allow to Dry: Leave the product on the surface and allow the remaining water to evaporate naturally.
- Reapply as Needed: Use after washing or exposure to moisture to maintain corrosion protection.
PRO TIP: Keep a dedicated spray bottle of diluted Atom-Mac ready in your detailing setup. A light mist over brake discs and wheel hubs immediately after the final rinse can help prevent the orange flash rust that often appears while the vehicle is drying.
Dilution calculator
Pick your container and your ratio, and read off how much concentrate to pour.
A foam cannon does not spray its bottle. It draws from the bottle into the pressure washer's flow, so a 1 L bottle can put 11 L on the car and the ratio in the bottle tells you nothing about what reaches the paint. Measure your setup once and the number holds for every product that quotes a PIR.
Common questions
-
Parts water to one part product. A 10:1 mix is ten parts water and one part product, so a 1 L bottle takes 91 ml of product and 909 ml of water. A few brands print theirs the other way round, so check the label if a number looks unusually strong.
-
Water first, then the concentrate. Pouring concentrate into an empty bottle and topping it up makes it foam over the top, and you lose some of what you just measured.
-
Most diluted products keep for a few weeks in a sealed, labelled bottle out of sunlight. Write the product and the ratio on the bottle. An unlabelled trigger bottle is how the wrong chemical ends up on someone's interior.
-
Panel Impact Ratio is the concentrate as a percentage of everything leaving a foam cannon, the bottle water and the pressure washer water together. It matters for snow foam and pre-wash only, because a cannon draws from its bottle into the washer's flow rather than spraying the bottle.
-
A syringe or a measuring jug with millilitre graduations. Capfuls vary by bottle and by how full you fill them, and at 256:1 a few millilitres out is a noticeable change in strength.
