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 estimated based on dry, room-temperature environment ,

Fantastic upgrade from my original stand. Base is a little bulky, but stand is versatile and sturdy.
Size: Single, Style: Free-Standing, Size: Single, Style: Free-Standing
Amazing value for this stand. I needed a stand with more degrees of freedom than the original one that came with my monitor, and this stand (which was inexpensive relative to the cost of the monitor) was a great purchase. The base of the stand is a little bulky/high, and the soft material on the bottom of it can rub off very easily if you let the stand catch the back edge of your desk. Otherwise though, the stand is extremely easy to install, and it provides far more degrees of freedom for rotation and translation than the original stand for my monitor. Now my monitor is sitting at a comfortable viewing angle closer to my desk tilted slightly upwards toward me. Just keep in mind that you have to tighten down the height and tilt adjustments (the things that would be affected by gravity). So, if you want to adjust those frequently, this stand might not be a great fit for you. That said, it does provide a hidden but easy-to-access spot to store the keys needed to loosen it up to make those adjustments. So, if you need to make those adjustments, you'll always have quick access to the necessary tools. Highly recommended for its price in particular.

A Solid Monitor Stand
Size: Single, Style: Free-Standing
This is an extremely sturdy monitor stand. Easily assembled in less than 20 minutes. Instructions were simple. The hex tools came with the stand, but you just need a Nr 2 Phillips Screwdriver for the bolts mounting the VESA plate to the monitor. Take note that this stand has a heavy base to hold larger/heavier monitors up to 22 lbs, but does not take a lot of space. I chose this variant so that it could handle my heavy 24-inch Planar monitor. The included cable management clip was a nice touch. Rotation and tilt feature moves easily and has decent range. I'm very happy with my purchase and it was available for overnight shipment in my region.

WALI Dual Monitor Stand: A Solid, Space-Saving Base Camp
Size: Dual, Style: Free-Standing
WALI Dual Monitor Stand: A Solid, Space-Saving Base Camp I needed to reclaim some real estate on my crowded desk, and this WALI freestanding mount did the trick. It's a straightforward, no-frills solution that holds my two 24-inch monitors securely and opens up a ton of space underneath. Assembly is intuitive, though having a second pair of hands is helpful when you're attaching the monitors to avoid any tipping. The all-metal construction feels sturdy and reliable. The adjustments are basic but effective—you can raise or lower both monitors together on the central pole and tilt or swivel them individually to get the angles just right. The included cable management clips are a nice touch for keeping things tidy. The key thing to understand with any freestanding mount is balance. If you extend the arms all the way out toward you, the whole unit can get top-heavy and want to tip forward. I keep my monitors positioned more centered over the heavy base, and it's perfectly stable. It's not meant for dramatic, extended poses. For the price, it's fantastic value. It doesn't have the infinite, fluid adjustability of high-end gas-spring arms, but it doesn't need to. It lifts your monitors, frees up your desk, and does its job without any fuss. Bottom Line: An excellent, budget-friendly way to lift two monitors and dramatically increase your usable desk space. Just be mindful of the center of gravity and don't expect ultra-flexible, independent positioning.

Easily supports a pair of 26" displays
Size: Dual, Style: Free-Standing
I have no complaints with this stand. It is not as nice as the Inland brand sold at MicroCenter, but it does its job. It beats the price of the MicroCenter one, thats for sure. It comes with all the hardware you might need, even long screws and bushings if you have a display that needs them. Assembly was quick. It comes mostly assembled anyway. You have to put the bottom on the post then attach the assembled arms to the post. Setting up can be a challenge but with help, its easy. After mounting the bracket on the back of the displays, you just slide them into the receiver on the arms. Once mounted, adjusting the position is simple, but can take a while as there are several joints which can be positioned to angle the displays as you like. The cord clips do an OK job of cord management, but the clips are not as good as the Inland ones. They do the job, but not as durable. I broke the one that goes on the post, but I tried getting it to hold a wad of wire. My fault. I recommend this stand.
