Best paint for protection against rust

[Macpherson]

Yeah, there`s no doubt in my mind that the powder coating of new things is no substitute for properly painted things, as used to be.

When I`m restoring things I generally take the bits to the powder coater to get blasted and then paint the stuff properly myself or get it galvanised. Imo there isn`t a short cut to a long lasting finish, cheers.

Hi Mac your right there it all so about preparation of the material as it's all out in all weathers just look at today hammering down with rain so the machinery is really going to take a beating thanks John

What thickness steel should survive galvanising is is it all about how well it's braced?

Box section is generally OK as long as properly vented (drilled). Its plated areas, especially thin plate such as panels and guards that will wobble big style.

Bracing is good for hot dip galvanising but can distort, for thinner sheet you can get things electro plated.

I'm afraid i just can't be bothered to paint stuff anymore- just cover everything in Waxoyl:laugh1: Not the prettiest but does stop stuff rusting and is cheap and quick.

I hate buying a nice shiny bit of machinery only for the paint to start coming of a year later.

Haha that had crossed my mind Matt. Thing is folks seem to like me turning up with a smart looking processor not sure what reaction I might get with it gunked up with waxoil

Ditto!

 

For my needs powder coating is rubbish, they sell all the reasons why its better. If they didnt prep right to start with it doesn't last. It chips, It fades in lighter colours in my experience, That is not scientific experience.

 

I have used rustseal from kbs, Flag rust preventer and kurust. They all work to a degree as primers for rust sealing but dont last forever especially in salted road environments. My previous tractor mudguards rotted to almost disintegration in 19 years without any maintainence. In less than 3000hrs work!

We have just upgraded to a 10 year old John Deere and I have commenced refurbishing rusty parts. The washer bottle bracket disappeared when i put the angle grinder wire brush to it. I refabricated another one and have used Kbs rust seal. Also did the small black wings near the steps. This will be my first acid real world test for rust seal.

 

Prevention is better than cure as is nipping it in the bud. But its the ongoing enemy....Time. Like Matt says seal it with a lubricant old oil etc. Underneath it will preserve, look how engine blocks with oil and diesel scud on them powerwash up fantastic after decades.

Some concrete mixer drivers paint oil on the drum to stop concrete adhering which then needs acid or hammer to remove. Which corrodes and dents the paint off.

Back to bare metal, clean with acetone, etch primer then coach enamel. Always worked on my MGBs.

BONDA RUST PRIMER ZINC ANTI RUST PRIMER is great paint, but you cant paint a top colour coat for one week if you apply by brush.
