Dinitrol RC900 and cavity wax

[Al Strachan]

Behold, the rear arches/chassis of a Nissan Pathfinder. basically they get the same tin worm chassis problem of a Navara without the snapping in half bit.

i'm going to run this thing into the ground and it's 7 years old, so taking the time now before the welder gets dragged out. existing paint on the chassis is vanishing, and some pitting/scale starting to appear in the problem areas.

Outside is in hand and i know what i want to do with it as you can see below and i'm cleaning, descaling, and using copious amounts of phosphoric to get a sound surface for painting, then a couple of coats of epoxy primer before anything else.

As for chassis internal, from what i can see/feel, it's getting a bit crusty, but no major scale. I intend to run a drain cleaner power washer attachment through the chassis to get the loose stuff off, then dry and use Dinitrol ML cavity wax.

Question is, should i be using RC900 first? i've done plenty searching on the forum and web, but cant find anything conclusive. Wondering if anyone has any experience after extended use? Not cheap stuff, and wondering if a good coat of cavity wax will be sufficient?

The consensus of opinion here was there are better waxes, but cant remember what

Mike Sanders grease, would be the best, never used it myself but was told that if you put it in an open jar it creeps out in a few days time.
It's applied hot with a preheated three meter long tube inserted into the chassis.
If the car is standing in the sun it creeps further into al cavities.
Before pressurewasher cleaning you can put a barbed wire in a drill and scrape some rust out of the chassisrails

I have similar plans for my Land Rover but just never got round to it yet , also want to do all welding first since the grease is of course combustible, and impossible to remove ever(!?)

I’d give the chap at rustbuster a call. He’s always good to chat with and get advice even if you’re not directly buying his stuff.
Looks like you’re doing a thorough job there.

from memory that RC900 is a lot like the FE123 from RB? I have used the 123 a fair bit and it does what it says. Actually it’s not bad being left for a while with nothing on top so I think using it first and then a wax over the top could only be a good thing.

I knock up my own, bitumen paint with some waxoyl thinned down white spirit just enough to pass through the gun/tube,cheap and lasts just as long
