    The logic of filling chassis rails with oil is flawed on many levels.
    You can bet your boots it is. Who would be stupid enough to consider that?

    I mentioned something I had heard, and Soundman has pointed out some of the flaws in "that someones" argument/discussion. I am not trying to make an issue of this. I am happy if someone points out the drawbacks applicable to what I have mentioned "I have heard about" or anything else. That's good. Everyone learns. I just have to laugh tho, when someone points out the self same flaws in an argument/discussion(?), but they clearly have not read the relevant post properly. I could never understand why anyone would would spend all that time arguing against something that was never mentioned.

    My point is

    Read the post you are answering properly.
    Answer the actual specifics of that post, or point out that your words are unrelated.
    Read the post again and delete what is irrelevant.

    Soundman, you have offered some good suggestions, but can I offer some advice. Read the post, because when someone answers one of my posts with an opening statement that clearly indicates they have misread it, you don't get your ideas across to me, at the very least. If you wish to comment on an even slightly different meaning, it is accepted practice to state this fact.

    I appreciate everyone's input, despite the turn this thread has taken. Some informative stuff from my perspective.
    My apologies Legion. I only wish I could help more with your question.

    I am afraid that this forum (Metal Work) is starting to go the way of another one over the pond. I wish every member would recognise that they are just offering their advice and expressing their opinion without trying to add another slant to the subject. I know of a number of members that have either decided to stop posting, or are considering this. If it continues I will also do so.

    I've learnt heaps off this forum. Only a few years ago I'd never welded in my life and now I'm tigging and stick welding every weekend, loving it and learning every day. Lots of reading here and other forums (even those American ones) and guys who have more experience than I ever will short track the path for me.

    I've already built one trailer and consider it probably better than a lot of mass produced ones. Of course, it was highly customised so I sort of had to build it or pay even more of a fortune than I spent but simple things that I remember dazzler posting, like don't weld across the drawbar (e.g. where the front chassis cross member is is obviously the main spot you'd be tempted) and tie the front spring hangers in to the drawbar. Little things like that that I might not have even thought twice about but now wouldn't even consider.

    And this thread - well I have major concerns about salty air so that was what prompted it and despite my question there have been a number of thought-provoking ideas and alternatives mentioned.

    Right now I'm also building some fence panels that will be partially in the ground. They will be galvanised stock (most likely, because that's what I've got lying around) and I will prime and paint them, probably with Dulux Metalshield family because it's the most readily available for me. I might also paint the in-ground parts with bituminous paint for extra waterproofing over the epoxy enamel. Not sure if that's appropriate. And there was one tip in here from someone about how galv stuff rusts especially fast when in salty, wet ground like this will be. So rather than find out myself the hard way in a few years if I just left it plain galv, that tip will ensure I take care and prep and paint it properly and get the best possible results despite my hatred of prepping and painting. The missus said to just leave them galv to save time and she doesn't mind the look but I don't mind the extra time now and I quite like the epoxy enamel look.

    So the point is, metal noobs like me learn heaps. I'm sure there are others who don't post but just read who learn heaps too.

    I have had issues with rabbits and a dog, who has now gone to her maker. The end result was a number of galv steel sections that corroded due to contact with damp ground. The contact was that they were buried in the effort to find the rabbits, and the damp ground was in my implement shed. Nothing around here stays dry in winter, even the shed floor. That was a learning experience. I am now trying to arrange everything I can on a small concrete slab that used to house the 32v generator.

    I generally use Killrust paints (much the same as the Dulux) and I have found it can do an extraordinary job given the right conditions. I have to agree with the suggestions to use paint. I do not live near the sea and I don't have problems with galv corroding if left unprotected.

    I'm assuming the gal stuff you have is Duragal, and it is a mighty thin coating that, as others have mentioned, doesn't last long once in contact with the ground.

    If you want a *really* good rust coating, go to your Dulux trade centre and get some Luxaprime ZP (it's an industrial product, so you won't find it in Bunnings). If it's going over new Duragal you'll need to etch prime it first, but if the coating's gone matte/cloudy, it should be fine to go straight on. A couple of coats of that stuff and you're sorted.

    Everything we've built on the farm in the past 20 yrs and painted with Killrust HD Primer and Killrust Epoxy Gloss Enamel has not rusted. Everything else has rusted away in harsh conditions. Gate trailers, plant trailers, fuel trailers, farm machinery, etc etc etc My trailer build elsewhere on the forum will get the same treatment and it will see me out.

    I bought 4 litres of Dulux Metalshield to paint my shaper (WIP also elsewhere on the forum) because that was the only one that would give me the sort of colour that I wanted, Dance Studio . I hope the shaper does not go rusty because I did not use Killrust for once . I have not used anything except for the gloss enamel straight onto metal that has only had wire brush cleaning. The only fail has been aluminium colour on the underside of verandah roof sheets, sprayed on. It is peeling off. The sheets are about 30-40 years old and had small patches of whitish corrosion which were wire brushed by hand. Maybe these needed more attention. Too late now tho. They are not coming off.

    wrt to closed sections, always a fan of drilling holes in a couple of places at least.

    Drilled more of my fair share of trailer chassis and steel verandah posts over time. (Fitting/repairing/modifying tent trailers... blind installation)

    Surprising how much water can get in and stay trapped inside.

    I will never be the person who has everything, not when someone keeps inventing so much cool new stuff to buy.

    From an early age my father taught me to wear welding gloves . "Its not to protect your hands son, its to put out the fire when u set yourself alight".
