Hi Guys,

I have the tar up and the pans look good. Just a little surface rust around the edges. I've been using the heat gun / putty knife / wire wheel technique to remove the seam sealer and I'm about halfway through. I haven't found any rust at all under there and am wondering if I shouldn't just leave the seam sealer in place on the other half of the floorpan.

Or...should I remove all? Should I reapply new seam sealer before ospho and primer...or just leave the seams bare?

IMO. OSPHO, epoxy primer, then seam sealer. Seam sealer is the weak link. After that I'll spray on 2k primer to start the paint process.

Thanks. Do you recommend removing the existing seam sealer? Seems to be intact and the metal below is perfect.

To be honest. I am in some spots. Not in others. (total car restoration)
Passenger compartment floor, yes. Back panel to rear trunk, yes.
Tire well of front trunk, yes.
Then it depends on what the seam sealer edges look like. Then the angle, could water collect there?

Remove all of it, you may eventually regret it if you don't do it now.;4

Your in a rainy area. I would remove all of it. I have seen many California cars start to rust under the seam sealer.

But the process for reapplication is exactly like Cary says. Good primer (Or high zinc primer if you have it), sealer, then prime again with your 2k or whatever your going to use prior to paint.

Thanks, fellas!

I thought we were talking about seam sealer around floor pans?

..........yup, got a bit sidetracked on an earlier hijack of the thread
