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 ,

Great ball
I have bought two of these in different colors. My Yorkie loves them. They’re very interactive even if you don’t put the cover on it they move and if he’s not playing with it, it tends to go into sleep mode.My Yorkie got the cover off the ball within the first two minutes. But he loves the ball. Now bought 2nd ball. The ones with covers don’t work he rips the covers off.

Super Fun
Color: Green
One of the most entertaining things you could buy. The dogs go crazy over it and have so much fun. It's a bit loud on hard floors, but honestly worth it for the laughs. Seems pretty durable too. I have 2 labs; one started out uninterested and the other started off scared of it, but not too long after, they both started going crazy, tossing and carrying it around while it shook.

Great for dog who loves chewing small “tags” on stuffies
Size: Rabbit & Pig
My dog loves chewing the small tags or ears etc on plushies. He will pick one ear to chew on the little stuffed dogs from Petco, chew it until it’s starting to get shredded and I have to cut it off, then switch to the other. I picked these toys specifically because they have SIX little tag-like parts that stick out, not just the two ears. He loves them! He is a 10 lb maltipoo and can easily grab and run with these. Loves the crinkle paper inside, loves the squeaker in the head, and LOVES the little parts that stick out for him to chew. We just got them today so time will tell if they are durable, but they seem well constructed and he’s happy, so I’m happy. Update: it’s been a week. I gave him one of the toys and he of course chose one ear to focus all his chewing on. That ear has been chewed and chewed and it is just getting to the point it’ll need to be trimmed off soon due to raggedness. Then he’ll still have five little nubs left on this toy to chew. So it should take him at least 6 weeks to chew all of them. By comparison, when we get cheap stuffies on Amazon, usually both ears are totally finished within a week or ten days. This is definitely more durable and worth the money!
