Hi all,
Have got a set of 2nd hand suspension springs, and the original coating is flaking off. I want to apply some pretty permanent rust protection, and it seems that powder coating might do the trick. Is this a good idea? Will it last long with the flexing of the springs? If so, does anyone know of a good powder coating place in the S. Wales area? Google throws up a few places but I wondered if anyone could recommend somewhere good/cheap.
Thanks in advance!

Powder coating is okay on springs where there's little deflection (ie stiff ones). Generally big springy ones use plastic coating.

I've done it with loads of springs - hangs on pretty well - better than wet paint IMO  |

I think the springs for my car fall into the "big springy ones" category. Can you tell me a bit more about plastic coating? Ta.  |

From what I recall from A level DT it involves heating the metal up and dipping it into a trough of plastic beads/powder. Similar to powdercoating but you and up with a much thicker and more flexible coating. |

I've had motorbike springs plastic coated and looked OK for years.
I wouldn't be surprised if the existing flaking finish is powder coating. All it needs is a nick that allows water in and it'll rust under the finish until it flakes off.
Personally I'd just use decent primer / paint as easy to redo every so often whereas plastic or powder coating is difficult to remove (chuck in fire ?) if it deteriates.

 Striped with a knotted wire wheel in the grinder then rust treated then sprayed using red enamel from a tin. |
