just checking, when restoring the car and re-painting it, do the leaf springs get separated and sprayed both sides. I suppose they would but only the top and ends show??
Thank you in advance. Bob
Bet to do what Ford did, apply a graphite based material first. The leafs need to slide on each other.
Slip Plate or EZ Glide.
Robert - Reading forum threads on this, I refinished my leaf springs in these steps:
1. Disassemble the stack
2. Clean all leaves, all surfaces (I used angle grinder with a rust/paint removal wheel).
3. Paint all surfaces with two coats of "EZ-SLIDE" graphite based paint.
4. Assemble stack.
5. Paint assembled stack with your choice of top-coat paint.
So far, it's worked out well for me.
Here's the paint I used
Front spring leaves, painted before assembly.
Rear spring leaves, painted before assembly.
I paint the entire leaf. The paint will wear off where it rubs. I just use chassis grease in between. That also works out where they rub. Some folks use teflon tape but it adds thickness as sometimes shifts.
I clean the leafs then only coat the underside of any rubbing leaf with paint/graphite mix. I then paint the assembled spring. I make my own EZ-Slide out of flake graphite and enamel paint, heavy on the graphite.
Dave states he painted all surfaces with EZ-glide and then painted the stack. I painted just the top and bottom of each leaf with the EZ-glide. Then I assembled the stack. And lastly I painted the entire stack.
Wherever there was EZ-glide on the leaves, the paint would not stick. Perhaps Dave used a different type of paint.
The spring is reinstalled in the car and time will tell as to whether there is protection from the EZ-slide where I could not get the paint to stick.
After I coat the mating sides, top and bottom with the EZ Slide, I assemble everything. Be sure to only eye ball two leafs at a time, because sometimes each side is not the same, and you don't want daylight showing through the leafs after assembly. I then clean everything at least twice with a clean rag and solvent to make sure there is no grease on the exposed spring, and then I paint. I've done dozens of them that way.
Dave - I used good old Rustoleum gloss black on top of the EZ-Slide graphite paint. I had no problems with adhesion of the gloss black straight out of the can (brushed, not sprayed).
I used UHMW tape. This is a dense teflon type material. I put it on the underside of each leaf in 2008. It is still working well and has not extruded from between the leaves.
I got it at McMaster-Carr :

Here's another thread on UHMW tape:
Teflon tape applied while the paint is still a bit tacky.
Apparently there are several ways to skin this cat. I disassemble the spring, then have it sandblasted and powder-coated. Then I spray the undersides of all but the bottom leaf using the graphite spray and assemble them. This way, I don't have any rust bleeding out from the leaves when I drive in the rain.
I forgot to mention that I painted the leaves with POR-15 before I taped them.

One thing you may want to check on each leaf is to see if there is an indention where the next spring on top has worn a spot that will actually impede the springs from moving past the indention from decades of use during driving. This can be remedied by grinding the underside end to a slight bevel, not as drastic as the taper leaf springs, so the straight edge doesn't get caught in the indention. Just a suggestion that has worked for me. This does not forego the need to clean, paint or graphite / grease the springs.
I paint with Rustoleum and lube with bees wax..............
Robert, that is interesting. What is the advantage of bees wax over mineral based grease?
Where do you get EZ-Slide paint?
Tractor Supply, Amazon. Maybe local auto parts store. Mine has it. Its a Mom and Pop real auto parts place.
Eric I use it for all kinds of lubrication....I keep a fresh toilet bowl wax ring on the work bench. Works great on threads, drill bits. I lube the oil light slide rings any thing that binds on the paint. It is very friendly with paint, just wipe up with mineral spirits. A friend of mine said he kept a ring on each floor of his house when he was building as it helped all the wood screws he was using. I also use it on rims to mount tires, again it cleans up nice and feels ok to the hands. I think it will last between the leaf springs just has well as something else.
Make your own, and I will repeat it, make your own.
My 1919 Touring listed slightly to the drivers side before I refurbished the springs and upon inspection it was not because of stiff spring hangers. A local fellow advised grinding smooth any divots made by spring ends and upon assembly after graphite/grease application to assemble the springs with every other leaf turned in the opposite direction it was originally. Don't know how true his advise was but the car sits level now.....
Robert Stingley, As you know most Model T owners are frugal to the point of being CHEAP when it comes to spending money. You might want to inform the group that it is ok to use a new toilet bowl wax ring and not one that has been sitting under a toilet for 50 years....
PS- Sorry I spelled Skingley incorrect. I ought to know better since my last name gets butchered all the time. Obviously we cannot edit a post with this software.....

Mark - sadly I do not see such a list when I go into my own profile. Where is it hidden ?
I do not see the list either.

Robert S., if the toilet rings are made of beeswax here, I will definitely be trying them out for general lubrication jobs. That's a really cool idea.
And thanks for the heads up Michael P. I'll be sure to buy new ones! ;)
