4 x DINITROL ML PENETRATOR RUST PROOFING CAVITY WAX 500ml AEROSOL + EXTENSION

The long extension wand with 360 injection spray pattern makes it perfect for injection of box chassis giving all round coverage internal

Easy to apply, a lot easier, less messy than waxoyl. The 360 extension nozzle is brilliant, got loads of wax into chassis box sections and subframes.

Dinitrol ML Cavity Wax supplied in these four 500ml aerosol cans contains rust inhibitors, remains flexible with a small degree of self-heal, and is a major part of the superb Dinitrol anti-corrosion system. I found that four cans are sufficient to apply a reasonable protective coating in the relevant places on a carefully cleaned and dry low mileage and rust-free MX-5 (a small car), enough so that I used the last part of a can just finding nooks and crannies and bolts underneath that might have been potential rust traps in the future. The 600mm extension included allowed me to reach far enough into all cavities without too much dismantling after having removed the wheels and wheel arch liners. If you really want to go to town and soak everything everywhere and have it dripping out the drain holes then at least double the quantity will be needed; and to make it much easier use a proper Schutz gun with metal pick-up tube and high capacity air compressor, however I don't see the need for this. Over the last fifty years of motoring when using the original version of Waxoyl etc on my other cars I only protected the most vulnerable areas (insides of door seams, all door pillars, all sills, boxes, sub-frames, wheel-arch seams, etc, but left most large panel areas unless they could have water running over them); and most of those high mileage cars lasted close to twenty years rot free with only unrealistically expensive mechanical problems forcing their being scrapped. Be aware that this cavity wax will not fix rust. Light surface rust can be 'converted' and stabilised with RC900 ; but flakes must be removed first, and deeper more structural rust must be replaced with new metal and properly primed. To resolve any doubts about the condition of the metal work prior to treatment a small borecam inserted into the cavity can sometimes be a great help. The ML has a brown colour which gives a useful indication of how complete the coverage is. As usual with an aerosol it helps if the can is warm and given a really good long shake before use, and the car is not cold. Mask off anything that should not be sprayed, such as exhaust, brakes, radiator etc. If the area to be protected is going to be sometimes visible, such as in the engine compartment or boot, then instead use the 1000 clear wax which dries hard. It is essential to work in a warm well ventilated area, and very worthwhile to wear disposable protective clothing, face mask and disposable gloves , and to invest in some benzene based cleaner to remove the inevitable over-spray. Place plastic sheet and/or newspaper etc underneath to prevent drips from marking the floor.

Does exactly as described. The long application tube is perfect for use in chassis rails. It literally goes everywhere and coats everything.

As I like to drive older Nissan's and they can have rust issues with the UK road salt I always spray all vehicle box sections and sills with Dinitrol, great product and this is the third time I have used it on a Nissan, totally recommended.

Easy to use, no smell left behind, very convenient cavity attachment.

Exceptionally good product, a bit more pricey than Waxoyl but its worth the difference if you value your classic

Easy to use and has done a good job
