can you paint this stuff over painted areas that have rust on them? how about on the leaf springs. should I then paint over the POR 15 with a coat of paint?

The POR15 actually makes a stronger bond to rust than bare metal - but you would want to knock any loose paint off with a wire wheel. You should definitely top coat it because it breaks down in UV light (rattle can is fine) -raoul reese said:

POR 15 works best when painted over rust or sandblasted surface, you can paint it over old paint but it wouldn't work as well.

Good Luck.

not sure I would paint over the leaf springs. that might bind the individual leaves together - they need to move independently for the springs to work.
People have taken apart their springs, taken off the rust, painted them separately and put them back together for the same reason.

I took my leafs apart, sand blasted them, painted them all with por15 plus a top coat, and they turned out great.

Do you think that not taking them apart would be a mistake. The leafs were in good shape six months ago. The flash rust I see now may not have penetrated into the pack. The leafs are unlikely to "weld" themselves together due to the POR 15. What do you think?
I think it would be a waste of time for you to POR15 the surface rust on your leaf springs. Leave them alone and they will still last much longer than you will.

I disagree, leaf springs can be compromised by rust to the point that they can break, at least up here in the northeast. But he's not gaining any protection by POR15ing the outside only other than making them look nice, which could be done a lot easier by spraying with Rustoleum. To protect the leaves from rust he's got to open up the packs and degrease and POR each one, and put them back together with teflon pads. in between. Also, no way you can "weld" the pack together by painting just the outside. The forces are way too strong.
Just my 2¢

The product is called Slip Plate. I get it from the John Deere Dealer, but it is probably available elsewhere. I paint the underside of my mower deck with it each fall. It is slick. I would think that it would be a great product to paint individual leaves of a spring pack.
The POR will degrade cosmetically, but the fading to a dull charcoal grey does not in any way hamper it's rust preventive qualities.
Either one ought to work just fine.
