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 ,

False advertisement of Real Batana oil 😡
Color: A, Color: A
This product is NOT real Batana oil , it smells like a hair relaxer it’s more of a Clay formula which Batan oil is more of a thicker formulaI. I don’t recommend the purchase of this product .This is what the product looks like after allowing it to sit in the microwave, it did not melt into an oil. This is the result of what it looks like after removing it from the microwave in picture number two.

Not sure it's pure Batana oil
I'm not a botanical expert, so I may be totally wrong about this, but based on the ingredients, I don't think this is pure Batana Oil. The ingredient list (typos included) reads: "Elaeis Oleifera Kernel Oil, Babassuamide DEA, AscorbicAcid, Phytosterols, Carotenoids, Vitamins c." The last 4 ingredients might just be components of the oil itself, rather than additives. But Elaeis Oleifera (American Palm) Kernel Oil is Batana oil. But Babassuamide DEA is an oil that comes from the kernels of the babassu palm, not the American palm. Sure, it's still "palm kernel oil", but if I wanted just any ol' palm kernel oil, then I'd use some out of the cooking oil bottle in the kitchen and save myself a buck. I wanted 100% Pure Batana oil. I also can't figure out why the description talks about it containing Vitamin E, when that isn't listed as an ingredient. If it's been added, then it definitely needs to be listed on the package. If it's a natural chemical part of the oil itself, and the same is true of the Vitamin C listed, then why not list both separately? Or is the Vitamin C listed because it's been added despite them saying it's pure Batana oil? I don't know. So if you just want some kind of palm kernel oil to moisturize your hair, and you're not particular about whether or not it's really pure Batana oil, then this might be the oil for you. But, if you're a stickler for purity, maybe not. And there are lots of cheaper Batana-type palm oils out there that aren't true Batana, if price is more important to you than purity.

Best self tanning mitt!
Pattern Name: 1 Tanning Mitt, Pattern Name: 1 Tanning Mitt
This self tanning mitt is perfect for applying the self tanner. It keeps your hands from getting streaky in between your fingers and the mitt is very soft so it feels like nothing when you apply the self tanning lotion. This sunless tanning mitt is so soft and doesn't absorb the product but applies it very evenly and effortlessly. There is a protective layer between the mitt and your hands so you won't get any lotion in your hands. I also used the latex gloves that come with the actual sunless tanner lotion as well for extra protection but honestly, I don't think I even needed them. The tanning mitt can be easily hand washed with soap and water and air dried after each use. I have never used two tanning mitts to apply self tanner before, but the self tanner came with one and I purchased a second one so I could try using two at once and I'll never go back to using just one, it's so much easier and quicker to apply the sunless tanner with two mitts. And if you are looking for a great sunless tanner, check out the sun labs self tanners that go with this mitt. I've never tried a better self tanner in my life, and believe me, I've tried them all. I would highly recommend this tanning mitt and the price is just right!

Four years going strong with this mitt
Pattern Name: 1 Tanning Mitt
This is the absolute best sunless tanning mitt hands down and itnonly costs 6 bucks! I've used the St. Tropez mitt, the Fake Bake Flawless mitt, a few different generic ones and I stopped searching after I found the Sun Labs one. It applies the tanner evenly & smoothly and it feels great against my skin. It's a plush micro fiber material that's the perfect thickness so it doesn't absorb too much product or make application streaky. It truly is the best mitt one could ask for! I love that it's black so the tanner stains don't show and it has a thumb hole. It fits literally like a glove and doesn't twist around during application. I bought it in 2018 and have used it every time I've applied self tanner since. It's in almost as perfect condition as the day I got it. At this rate I may never need to replace it. It holds up so well to washing. I wet the mitt, apply a small amount of dish soap, lather & rinse then let it air dry and it's perfect again. It never loses it's softness or shape. I can't say enough good things about this mitt. It has proven to be one of my best little Amazon finds and will never use another tanning mitt as long as I have this one.
