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 ,

must-try. Five stars from me!
Size: 4.2 Fl Oz (Pack of 1)
I recently tried the **ELBBUB Whipped Tallow Cream**, and I can confidently say it's one of the best skincare products I've ever used! From the moment I opened the jar, I was struck by the light, fluffy texture that feels luxurious and indulgent. This cream absorbs beautifully into the skin, leaving it feeling incredibly soft and hydrated without any greasy residue. It’s perfect for daily use and works wonders on dry areas, especially during colder months. My skin feels plump and nourished, and I've noticed a significant improvement in its overall texture and appearance. The ingredients are clean and wholesome, giving me peace of mind about what I'm putting on my skin. I also appreciate the subtle, natural scent that isn’t overpowering, making it suitable for anyone sensitive to strong fragrances. What truly sets this cream apart is its versatility. I’ve used it on my face, hands, and even as a body moisturizer, and it performs flawlessly across the board. It's become an essential part of my skincare routine, and I can’t recommend it enough! If you’re looking for a rich, effective moisturizer that truly delivers, the ELBBUB Whipped Tallow Cream is a must-try. Five stars from me!

So soft I love!!
Size: 4.2 Fl Oz (Pack of 1)
I have been using this tallow cream for months now and my skill feels so moisturized every time I use it. I have had it for a while and still have half of the jar left so, a little does really go a long way. I really wanted to switch to a natural product to avoid putting harsh/unnecessary chemicals on my face. I also have pretty dry skin which was another big reason why I wanted to try tallow for my face. It is fragrance free which is I do like. I have not noticed much of a change in my skin appearance, largely because I do already have good skin but I love the way it makes my face feel. I did not notice any major breakouts when I started using this product, though I have never had sensitive skin. My boyfriend does have sensitive skin though and he uses it from time to time and has never complained about breakouts. I think this product is worth trying, though everybody's skin is different so you just have to test it out and see!

Highly recommend
Size: 4.2 Fl Oz (Pack of 1)
This is a great product. I’ve probably ordered at least 10 jars at this point. I use it as my every day facial moisturizer. It’s not greasy, I’ve had no break outs, it has virtually no smell, and I love that there are no random unnecessary ingredients added. My husband (who has very sensitive skin) now also uses it as his dairy facial moisturizer. Highly recommend!

Very thick, rich cream. Good for hands or overnight.
Size: 4.2 Fl Oz (Pack of 1)
I like this, but I don't love it. It's very rich and creamy, no discernible scent, and feels good going on. The beeswax in this makes it a good "barrier cream", great for overnight. This is very moisturizing, but it does not seem to penetrate as deeply as another tallow cream that I tried which has no beeswax. It's a nice sized jar for the price. This is really good for hands. I'm still on the hunt for a really good tallow cream that doesn't contain wax or olive oil...the search continues.
