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.

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 ,

Amazingly nice watch!
Color: 2942 Silver Black
I'm a big watch guy. I own many watches, of various brands, styles, and colors, along with both an Android and Apple watch. I like being able to pick a watch that goes just right with what I'm wearing. All that being said, this watch is an excellent addition to my collection, and here are my thoughts after having worn it multiple times. This watch looks incredibly nice and is very well made for the price. It's currently around $50, and that's amazingly affordable considering the quality you get. I have the Silver Black version and it's gorgeous. It keeps time without issue and is easy to read, even in the dark thanks to a special coating that absorbs light. There are additional smaller dials inset that are also still easy to read, despite the smaller size. Setting time and date is easy, and I was able to adjust the band easily with the provided adjustment tool. This watch is on the heavier side and I like the feel of it, but I know some people prefer lighter watches, so keep that in mind. Nevertheless, I find it comfortable and classy. Overall, I really like this watch and I highly recommend it. At its current price, it's an instant buy.

Bold and Eye Catching Watch That Adds Style to Any Outfit
Color: 2942 Black Red
I picked up this OLEVS square face watch because I wanted something that stood out more than a basic everyday watch. When it arrived, the first thing I noticed was how bold the design is. The large face and black with red accents really catch your attention, and it gives off a stylish look that works well with both casual and dressier outfits. One thing I really like about this watch is how much detail it has. The multiple dials give it a more high end look, and it feels like more than just a simple timepiece. The weight feels solid on my wrist without being uncomfortable, and the strap fits well once adjusted. I also like that it is easy to read the time, even with all the extra design elements. There are a couple small things I noticed after wearing it. The larger face may feel a bit bulky at first, especially if you are used to smaller watches. The design is also very bold, so it may not match every outfit depending on the look you are going for. Even with those small things, I have really enjoyed wearing it. It is a stylish and eye catching watch that adds personality and works well when you want something a little different.

Love the squarish shape dials are cool and helpful. ❤️‍🔥
Color: 2942 All Blue, Color: 2942 All Blue
There's a lot to love about this watch. The squared profile gives you that big watch look without being gaudy or ridiculous. The blue with gold accents look great with both dress and casual clothes, especially denim. I love this watch's features and I've gotten multiple compliments on it. great value all around. Here's what stands out to me: ✅ The blue with gold accents are really stunning and unique. I've had people start conversations with me over this watch. 👍 ✅ The squarish shape is complimentary for average and smaller wrists (doesn't look too bulky.) ✅ Gold accents look very distinguished, and the blue is great with jeans or a blue suit, very unique. ✅ The sun and moon dial is a beautiful feature that makes me happy. 🤷😅 ✅ The 24hr time dial is extremely helpful. I need to refer to military time so that's nice. 🪖💪 ✅ At a glance, the hands and accents are great for far-sighted folks like me. ✅ It's nice to have a date window at the bottom for quick reference. ✅ The linked watch band is comfortable and has a great symmetrical and slim profile that doesn't add bulk and doesn't pull at arm hair. ✅ The band does not sound hollow or jingle. (why I shake it in the video) ✅ The buttons and time setting are easy to access. I'm really enjoying the quality and look of this watch but if there are any changes in my opinion or its quality, I'll be sure to report back in. 🤞 I hope you found my notes, pictures and video useful. Be well! ❤️‍🔥

Highly detailed inner face wide and big very manly for a deserving man...
Color: 2942 Silver Black
On par with other Men's luxury Chronograph Dress watches with one exception that levels this up. This has a luminous markers activated when exposed to bright light for 20 seconds. That is something I really like, and not commonly found anymore. My other men's watch is a mechanical swiss watch that you can see the movements and rotaries inside very detailed. This may not have that but this is still very luxurious looking and feeling. This has the luminous markers while my other one doesn't but to be fair, that other one costs above $90, so this was a fair price for this luxurious Men's watch. I find this durable and the clasp gave me no issues.
