What Is Good Anti-Rust Paint?

[abrogard]

Here in Australia we typically use a paint called 'Wattyl Killrust' to paint our car trailers. Thousands of us have these little 6foot x 4foot box trailers we pull behind the car and use for taking rubbish to the tip and many other little odd jobs. They are a sort of standard suburban accessory.

Knocked about it use and sitting out in the yard or backgarden and neglected for years these trailers often get rusted here and there and owners want something to repair the damage and protect against future damage.

This paint refers to itself as a 'superior protection epoxy enamel' and the last little tin I got was 250mL for $13.90. That's about $55 a Litre. More than $200 for a four litre (that's about the standard size) can of paint.

And it is just not that good. If you really want to 'killrust' you'll have to well prepare the surface and use their proprietory primer.

There's other products out there. I got some kind of acid the other day that claims to convert rust. I've used it but won't know how good it is for some time.

What do the forum members reckon? What's the real value of products such as 'Wattyl Killrust'? What happened to Red Lead? Illegal today because of lead? Would it be just as good to use anything at all given that rust can't continue in the absence of oxygen and many paints (all?) will bar oxygen from getting to the surface?

i think the main thing is prep.if you are able try sand blasting the trailer back to the virgin metal and then prime and paint.after a while it will rust again from every day wear and tear but it will take a while.if you can get akso nobel (sikkens) products there get some utech 3.8 (acrilic urathane) and a good epoxy primer.i do big truck frames with that and the drivers love it (very durable).you might look into por 15 it is a good product for going over rust but it must be top coated as it has no uv protection. it is not cheap ($70.00 qrt canadian).good luck.cyas

eastwood also has something like por 15 and tests have shown it holds a little better. rust encapsulator is what it is i think.

Thanks for the replies, guys.

I don't know if we get this POR 15 in Australia, I'll look around. And this Utech 3.8 sounds good, I'll look for that too.

Yep, back to the bare metal is best - but then any paint at all would do, if you see what I mean.

This product "Killrust" is supposed to do something special when painted onto a rusty surface that you've no more than scaled and wire brushed. So it sounds like the same kind of thing as Por 15 - except Killrust doesn't need a topcoat. It is not even supposed to need a primer.

And the price isn't as bad as I made it sound, either. If you buy small 250ml tins they'll cost that: $13. But twice the quantity is only $20 and four times the quantity is only $33 and I think 4litres is actually only $80 or thereabouts. That was my mistake. Just owning the one tiny trailer I've never needed large quantities.

At those prices I begin to change my mind about Killrust. It might be a good product in all respects, including pricewise.

But I'm still not sure. Is it doing something good or would any old paint do.

And since I wrote I've seen something that maybe answers that question for me. I roughly cut back a rusty patch on an old Volvo and painted it with some primer to hold it while I got around to painting it.

Now I see the rust is coming through the primer. The job's about two months old. If it had been painted with Killrust that wouldn't have happened.

so I think maybe i've answered my own question regarding Killrust.

Yes, it does something and it is worth the money.

This acid I've been using looks to be doing a good job. Phosphoric acid it is called. Cleaning the metal well, using the acid, killrust on top might make a good job.

If anyone knows of a better (i.e. could simply be cheaper) way please tell me otherwise I'll continue with it as the treatment of choice.

thanks for the input guys.

A quick google shows it is artificial money or cyber money if you like, for using with a computer game probably called 'runescape'.

You could have done that google yourself.

If you want to post questions on forums it's pretty good to pick a forum that talks about what you are asking about (I realise maybe you thought runescape gold was a paint, that's okay) and start a New Thread for your own question.
