Prepping Seat Springs?

2Loose

reliable source of info
Both my '55 chevies need fresh upholstery, neither one is a show car candidate, but I want to do a clean, serviceable long lasting upholstery job. And I am keeping the bench seats.

The seats are out and stripped on both cars, the spring assemblies on the hardtop will need a little adjustment in the rear to fit the minitub job, but look very good, surface rust is there, but nothing unusual.

The spring assemblies out of the 4dr are heavily rusted. I think they are still usable, but I want to clean up the rust. I thought about sand or crushed glass blasting them, but was advised against that on another forum, as the media will get into all the little joints in the spring structure and cause problems forever.

So need a way to clean up the rust and then best paint scheme for these two cars. I could just wirebrush the heavier rust wherever I can get at it, then treat it with phosphoric acid to "fix" it, then paint it. I like to use POR15 in a lot of areas of rusty body work, have been successful with it, and would like to use it here, but all the little joints in the seat spring structure would probably get glued up tight with that stuff. Not a good scene.

Anybody reworked a set of steel seat springs like this successfully? Any suggestions, ideas, comments? Once I commit to a course of action, I'll post the results here.

Aloha,
Willy
 
I could easily be giving you bad advice, but the last time I did that was on my 1965 tempest, and I used a sand blaster filled with very fine black pumice and it resulted in a great job, I painted the springs with that fine light green zinc, anti-corrosion aircraft paint and it worked great.

Hey 2loose,
The best way to finish seat frames is to have them sandblasted then powder coated. Any liquid paint you put on them will crack when the springs flex over time. Powder stays soft and flexible, which is exaclty what you need. The rust will be removed with the media blasting, and if the coater is doing them right you will have some seat frames that last longer than the car. When I blast seat frames I make sure and use media that is small enough as to not sit in the pinches of the springs. I have done thousands and have never had a problem.
