As above - does mordant solution basically do the same thing to galv as a light rub over with something like red scotchbrite? I still need to get on with my land rover chassis and the epoxy primer says to lightly abrade the galv. The thought of rubbing the thing down woth all it's nooks and crannies is stalling me. Mordant solution would be easier if it achieves the same thing.

Thanks! That should speed me up then!
If the solution gets inside the chassis does it 'weaken/thin' the galv that isn't getting painted at all?
Great. Thanks.No, it is just doing the same as weather would do.
(That's the lazy way, leave the galv out in the weather for a couple of years and then paint...)
Spray wax in once the paint is done for belt braces and piece of string
I should have left the darn thing out when I bought it. Been in the shed 5 years while.I procrastinate. I must get on with it!
Is there a particular brand of mordant that's better than others?! Or will any do?
not wax ,,, try acf 50, wax will cause issuesNo, it is just doing the same as weather would do.

Mordant for this is basically copper sulphate solution.
Just buy the mordant that is convenient for you.
It is also called T-Wash.
2 litres will do a Series chassis, about £15ish

Great. Thanks. All ordered. Its a 110 chassis so I got 5L to be on the safe side and I always have other bits of galv metal that I need to treat so this should last me forever.
I really need to just get on with this job so this should get me going. Seeing roof tents at a local show last weekend has made me realise that i haven't used mine for nearly five years and I want to get out with it again!

Why not wax Tom? This is a new galv chassis so just curious what issues it might cause.
Happy to use the best thing to protect it though so I never have to touch it again!

Why paint at all? unless you want to disguise the fact it will be on a galvanised chassis
All sorts of galvanised things get like trailers get left unpainted, is there any evidence to support the fact that painted galv lasts significantly longer than unpainted?

Partly to disguise, partly because I don't want it to look silvery and partly because I am sure galv will corrode eventually so I want to give it another layer of protection.

James' 90 in Scotland recently got regalved because the Scottish road salt had eaten through the original galv.

Unless the galv is very fresh , mordant doesn't work very well. If the chassis has had any weather at all it will be oxidised. Having used mordant t wash on my 2a galv chassis to poor effect, I would go with a though degrease, a quick rub down and then the epoxy.

I find , and many and every one will have their own ideas ,,, way especially waxol dries and cracks , then it actually traps moisture and causes issues , plus if you ever do have to go back for a repair etc wax burns , I use acf 50 and give a chassis a piff every couple of years , land rovers have plenty of holes and you will be doing outriggers floor x bars and rear x member too so ten mins extra makes no odds ,,, do some reading and see what you think . and I wouldnt be using used engine oil either , another farmers favourite ,
For my galv'd 90 chassis I scuffed it up lightly and used por-15 etch primer because I cant find mordant t-wash here, then the correct por-15 chassis paint on top of it. Having said that, for all the hype its not very robust, and I wish I'd have acid etched it and used 2k or something generic or coachpaint and that's the route I'll take on the next chassis I have to do.
I have a 5l tin of fertan to inject inside it when its back together fully before it sees use.

Im with you on this, why advertise it has a nice new chassis possibly with no numbers on it so someone steals it for parts because they can move it on easy, and why have it look like a cheap trailer finish.
