When restoring springs do you need to use primer before slip paint and/or the regular paint? Plan on using Rustoleum if that matters. Thanks, Dave
I primed and painted the springs while I had them disassembled so they wouldn't bleed rust. As I reassembled them I put a mix of graphite and grease between them.
The slip paint doesn't need primer. Most important is to round off the outer lower edges of every leaf so they don't dig into the next leaf below.
I made my own slip paint by mixing graphite powder in regular black paint, since slip paint isn't sold over here - and it's quite authentic, since that's what Ford used on the springs when new. If you don't like the greyish tone from the graphite, you can spray them with a black Rustoleum can after assembly.
John Deere Graphite Lubricant works well between leaf springs. Get it in a can and paint it on the surfaces of the leaf springs. Takes about 4 hours to dry. Then assemble springs.
I make my own slip paint also. I do not paint the springs till they are assembled.
Dave, when I did my springs,I had each leaf bead blasted, then I smoothed the ends of the leaves as Roger suggested. I painted both sides of each leaf with Rustoleum. I used Slip Paint that I purchased from Lang's and painted both sides of the leaves except top of the top leaf and the bottom of the bottom leaf. If you get a little of the Slip Paint on the edges as you paint just wipe it off. Don't let it dry or you'll have to live with it. The springs look and work perfect, and they're quiet too.
No matter which way you go, the ride will be a lot smoother although you may bounce a little every now and then.
Thanks everyone for the ideas, Dave
They used to make spring boots that helped keep the goop inside and on the springs...they had metal ties and a big piece of felt on both sides inside it...those worked pretty well...had a set on my A Model back in the 70's...I suppose they'd also work on T Models too (might have to shorten them down some though).
I just looked, they still make them and Snyder's still sells them too.
