I'm thinking about overhauling a pair of axles, at the moment they have no paint left on them so are rusty and a little oily but nothing a wire brush won't remove.
I am wondering what paint is best for the axles? And would having them shot blast and powder coated be a good idea?
What is likely to last the longest, pros, cons?

Regards
Liam

Afternoon liamh.
Be careful about what shotblasting material is used or you could end up with holes in the axle casing.
I don't know about the durability of powder coating on the axle. It gets a lot of grit etc thrown at it in normal driving conditions.

Paint.

Powder coating WILL eventualy crack and let water sit in between the coating and the metal, leading to rust and loss of your axle.

Paint and underseal plus wayxoyl would be my recommend.

Paint can be touched up, powder can't.

A thorough wire-brushing, and then smooth black Hammerite is lasting well on mine.

What appeals to me for the powder coating is that I give someone a rusty axle and a day or so later they give me a nice shiny clean one back to me. Without me doing any work!
I hate painting, never seems to last long when I do it.
I've been searching the various forums and have found arguments for and against both paint and powder coating.
The arguments against powder coat is that it will crack, I've only seen powder coat crack when it's been a thin coating on garden furniture, or little brackets for things.
I've have stuff coated in the past and years later is as good as new, but it's a nice thick coat with a clear coating over the top. Seems pretty tough to me when I've been trying to remove it from areas that I didn't want coating!

Still not decided yet !
Regards
Liam

As with all Landy choices, it'll come down to personal preference at the end of the day. Whichever way you go you'll be making the vehicle better.

Remember that painting is 90% preparation and 10% "painting". An abraded surface thoroughly cleaned of oil and grease is what you want.

And a good paint job will mature nicely, and still look good (not plasticky) years down the line.

Think I just don't have the patience for the preparation bit!

For longevity and if you're looking for someone else to do the work - shot blast and hot dip galvanize followed by etch prime and paint, or powder coat.

It is personal choice, but I have also seen professional thick powder coatings fail at about 2 years and need fully recoating. Complete stripping of a fire tender to get the pressure vessel off, cut in 3, shot blasted, etched, rewelded and recoated, then reassembled.

For me, a paint finish can be repaired in situ if it goes wrong. Powder coating alone, if it cracks, that axle's coming back off...

After a lot of googling etc. I've found that apparently powder coat should be pretty good on an axle after being shot blasted as the powder adheres well to the rough surface but the use of a powder coat primer is even better.
As for paint, there are loads of options but what seems to be recommended is to wire brush or shot blast the axle, degrease, then use a rust killer/converter, then either rust encapsulator and top coat or 2 pack epoxy mastic.

I'm thinking that shot blast and paint may be the better way to go now.

I agree with your change of finish - but as Alan said earlier, be careful with the shotblasting that you don't do any damage. I used a wire brush drill attachment, wire brush, and a lot of elbow grease.
