It's just my own two cents from years in the powder industry, but leaf springs are one of those "touchy" things you should only trust to a VERY experienced coater. Leaf springs have Delrin liners in between each leaf, a specialized (usually Teflon) item that does not hold up to the heat required to either outgas the metal or to cure the powder. Without them, you end up with too much room in between the leaves (which just gets bigger once the car is on the road) and ultimately creates a hazard both for the driver and others on the road. Imagine cruising down the highway at 70 and one of your leaf springs just decides to fall apart ... yikes.

New liners can be purchased but the aftermarket ones don't really have the best reputation. Do your own research before making a commitment. This is an older thread but not much has changed in the meantime. Leaf spring liner

Thats good information Leanna, I did remove all the plastic sliders and took just the bare springs to the powder coater. In discussion with him we decided to keep the film build down since the springs flex a lot and a thick film would likely crack.

Interestingly I bought these from Chrysler and they only had the plastic sliders and no Zinc interleaf's like my originals,

I did purchase a rebuild kit that has the plastic sliders and the Zinc interleaf's so I'm hoping that with the powder coating and the proper rebuild they will be better then the way they came and will standup and not get rusty for a long time.
