Dinitrol Corroheat 4010

I have been using some of this stuff lately. It is a "high temperature wax lacquer" that protects engine parts. It's a bit like Waxoyl to apply - it goes on heavily (maybe because I lost the nozzle and am using one off a paint can!) and you end up with great gobs of what looks like spittle running down in places. Sometimes I dab these with a paper towel - probably better to spread it out with a paint brush. But when it dries - eventually - it all evens out and forms an all-but-invisible semi-matt coating. In this weather it will be touch-dry in less than a day, but it will take several days to properly harden. I sprayed my new brake master cylinder with it a couple of weeks ago & it looks great - by which I mean you don't know it's there, but hopefully it will prevent the bare cast iron from rusting. It looks slightly softer than the raw cast iron, but you relly wouldn't know it's there. I just sprayed all my front suspension parts (newly zinc-plated) with it also, but I did so before assembling the wishbones, and that was a mistake. Where the pins go through the wishbones and into the bushes I had to scrape it all off again, as it had hardened enough to prevent the pins from going through the holes. If I had done it wet it would have been fine, but once it's dry it hardens like a thick coat of lacquer. Unfortunately it was not dry enough to prevent some dirty handling marks sticking to the items in places, where I had laid them on a dirty surface, so I had to Scotchbrite those areas and re-apply.
The new zinc plating has a slight blue-ish hue, and the wax has a slight yellow tint to it, so I think they have come out about the right colour once coated!
This product is new to me, so I thought I'd throw it out there. Got it from Frosts. Knowing me, I expect everybody else has been using it for years!

I've used it just as you have Hugo, it's great stuff. I've also done inside the bulkhead where the pipes are and inside the transmission tunnel, the vapour blasted bell housing and pedal box and various other bits.

Another recommendation from me.

Yes Hugo..great stuff...but get yourself another nozzel.....it really does spray on just like paint and not like the usual cavity wax sprays.....a quick coat on all exposed bolt heads/nuts and any thing else on the underside and suspension is well worth doing..all the best... Steve

Huh. And there I was thinking I'd discovered something new. Behind the times as usual! Frosts just sent me another catalogue - and they have other products which seem to do the same job. Plus spray finishes for cast-iron, aluminium and even stainless steel, to mimic the original appearance. Clever stuff! You would have thought my nozzle from a paint can would work, wouldn't you. Maybe it's just my sausage fingers.
