Non-removal leaf spring lubricant?

I have had good results using motorcycle chain lube. It sprays on like a very thin penetrating oil, then evaporates to leave a greasy film. It seems to stay on the spring leaves a long time. I do jack up the car by the frame.
 
This morning I jacked the car up and put the frame on jack stands so that the wheels were not touching the ground. Once the springs were unloaded it was fairly easy to wedge a flat head in between each spring and I sprayed some PB blaster graphite spray in between each one. I did the front and rear. Took her out for a spin and the ride was perfect. Thanks for all the input and suggestions guys!

Great stuff. You'll be right now for your season's driving.
When it comes to assembling a spring for long term use, I clean each leaf of all rust and crud ready for paint. I mix about as much graphite powder with the primer as it will take and cover all surfaces. When it is dry, you can leave what looks like a pencil mark if you rub it with your finger nail. I now have lubrication all over the leaves which will be there for a looong time. I paint the whole assembled spring black later ready for installation. Been doing that for decades and the first springs done that way still work fine.
 
Is grease the better way to go? I have been squirting a silicone lube with its little red hose between the springs.
 
Kano Industries (Kroil) makes a specific product that travels horizontally between spring leaves. Don't recall is it's their Penophite or Dryphite. Rattle can application.

If the springs were out of the car I would have redone them and used grease between the springs. I am really happy with the graphite so far, of course it's only been a week. But a marked improvement over what the ride was two weeks ago.

I think separating the leaves is the key
