I'm prepping away on my 65 F250. Doing everything possible to do as good of a job on it as I possibly can. Along the way here I've been digging out loose material of whatever Ford used back then in the body seams. Apparently sheet metal stamping technology in the 60's wasn't as advanced as it is today cuz there's seams all over it!
My local paint store sold me a tube of 3M Ultrapro sealant that seems to be an appropriate material. I'm wanting to do a clean and neat job on it so I'm wondering what cuts this stuff. I'm sure there will be excess to clean up and it's been my experience that a wet finger with the suitable solvent will improve my ability to get a smooth bead.
Doesn't say a thing about clean up on the tube tho. Anybody know?
If it's like most seam fillers, it should be sandable once completely dried. I got ours as close as possible and then just hand sanded the seam with 80 grit until I got the look I wanted.
I used 3M fast and firm seam sealer before I primed my truck. Just use your fingers to work it down into the seams (I used my pinky finger because it perfectly fit my rain gutters). It is similar technique to caulking in things an using your finger to make the bead nice. To clean it up you can just wipe it up.
I (jor) posted a similar question In September of last year and got a lot of really good responses. You can probably find that post; it is titled, "Bed Seam Rust Repair." Anyhow, two products were mentioned by several people: 1. 3-M #08302 and 2. AllMetal. Several guys noted that it would be a great idea to sand blast that area. I sanded and sanded and wire brushed and wire brushed, then primed. I haven't gotten around to painting it yet but I plan to sand and wire brush again, coat it with POR-15 and then go with either of the aforementioned seam sealers. Good luck.

I sand blasted the entire truck and then used my 1000 degree heat gun and got rid all of the original seam sealer. But I only had to reasal the rain gutters and the door skin to door frame seal.
