DINITROL RC 900 is a rust converter based on an organic chelate complex combined with epoxy resin. It actively converts the rust on the substrate into a stable organic iron complex. When the product dries, it forms an impenetrable barrier to further corrosion. DINITROL RC 900 penetrates about 7-10 times deeper into the rust than conventional rust conversion products and forms a dry and strong adhesive film that is suitable as a base for the lacquer structure and as a carrier for other corrosion protection products.

HOW TO USE
Step One
Before starting the DIY rustproofing wash the vehicle from dirt and grease and allow to completely dry
Once dry, mask up any areas that you do not want to spray. Wear suitable protective clothing and place plastic floor covering under the vehicle to protect the surface from product drips. You may also require a wire brush to remove any loose material to find the solid base metal.
Step Two
Treat any rust present on the vehicle with the specialist RC900 Convertor product
Remove any flaking rust and apply the DINITROL® RC900 Rust convertor to the remaining rust making sure the edges are coated to ensure a good seal. This will convert rust into a stable organic iron complex. Drying time is up to 24 hours
Step Three
Spray ML cavity wax into all vehicle underbody box sections
Using an injection pipe or extension nozzle start to inject the product into internal bodywork and chassis cavities. Please note injection pipes or extended hose are for cavity wax applications only and not for applying vehicle underbody coatings. Drying time is up to 2-3 hours
Step Four
Also apply a thin coat of the ML cavity wax to the underbody of the vehicle
Spraying a thin coat (light misting) of cavity wax prior to applying the underbody coating softens up any existing coating that may be present and helps with the adhesion of the underbody or stone chip coating. Cavity waxes also contain rust inhibitors whilst the underbody coating combats the highly corrosive effects of road salt and abrasion. Does not have to dry
Step Five
Apply the underbody coating 4941 over the underbody cavity wax layer, this can be done while still wet
In some circumstances when working in a cold environment it may be necessary to warm the underbody coating (up to the room temperature) prior to spraying due to being much thicker than the cavity wax. To obtain the optimum protection a typical thickness of 2mm wet should be applied this will dry to around 1mm. Drying time is up to 12 hours
Step Six
Finally remember to clean any excess or overspray from the vehicle
To clean equipment use Benzene based spirit. Your vehicle is now protected from corrosion, please remember to inspect the underbody annually and touch the coating where necessary to check the surface in more detail.
Drying times may vary based on the environment. Times are estimate based on dry, room temperature environment ,

Pros and cons at once
It smooths and brightens my skin, but it’s not very moisturizing, so I have to reapply it frequently. Expensive too

Excellent choice for a gentle daily lotion
I have dry, mature skin, so I’m always looking for a lotion that actually hydrates without feeling heavy or irritating. I’ve been using the Koji White Body Lotion and it’s been a really nice addition to my routine. The formula feels lightweight but still moisturizing enough for my dry skin. It absorbs quickly and doesn’t leave a sticky or greasy film, which I really appreciate. I like that it contains kojic acid and papaya extract. Over time my skin has looked a bit smoother and more even, and it definitely feels softer after applying. The lotion is pH balanced and free from parabens and artificial dyes, which makes it gentle enough for everyday use on my more mature, sensitive skin. Another thing I enjoy is the light, pleasant scent, it’s subtle and fresh without being overpowering. Overall, it keeps my skin feeling hydrated, nourished, and comfortable throughout the day, and I’ve had no irritation. It’s a good daily lotion if you want something moisturizing with skin brightening ingredients that still feels gentle.

Silky, Effective Body Lotion With Strong Scent
In the winter, my skin is prone to becoming very dry and flaky. I ordered this "Kojic Acid & Papaya Body Lotion - Exfoliating, Hydrating, Moisturizing, Skin Care for Sun-Damaged Skin" by Koji White hoping it could help keep my skin from feeling dry and itchy. I ordered this lotion in mid Dec 2025, and the bottle is labeled with a manufacturing date in late Oct 2025 and an expiration date of Oct 2028. I’d consider this a very fresh product. The pump works smoothly, and I didn’t have any trouble getting it to dispense lotion. The label lists Thailand as the country of manufacture. I also liked that the listing describes the product as vegan and free of animal testing. I’ve been vegetarian for about 30 years, so this matters to me. I’m aroma sensitive, and this lotion lists fragrance as one of the ingredients, which is always a gamble for me. I definitely detect tropical fruity notes, and papaya is listed in both the name and ingredient list. There’s also a noticeable floral scent. I don’t usually like floral fragrances, but the fruity and floral scents complement each other fairly well. Unfortunately, the scent is much stronger than I prefer and seems to linger. I really like how this lotion feels on my skin. It’s a little less creamy than I expected given how hydrating it is, but it applies smoothly and evenly. It absorbs quickly without leaving my skin feeling sticky or greasy. My skin feels hydrated and silky smooth after applying, and it’s made a noticeable difference in how the skin on my legs looks and feels. Unfortunately, I’ve only been able to use it on my legs when I’m wearing pants because the fragrance is too intense for me. I love the results and wish I could comfortably use it all over. Overall, I really like this lotion. It has everything I look for to help prevent dry winter skin. The only drawback for me is that it’s more heavily scented than I prefer. At the time of my order, the 250 ml (8.45 oz) bottle cost $20. Given the quality and performance, that feels like a good value. For people who enjoy more strongly scented products, this lotion could be an excellent choice. Since fragrance preference is so personal, I won’t be deducting any stars from my rating.
