rusting roof

Also, apply seam sealer.. after you prime. (If it's not bare metal sealer) Not before. Sand area with 400 (after primer) Apply seam sealer. And then Before you paint scuff seam sealer with red scotchbrite pad. and Spray.

rusting roof

Take a 3M Purple Roloc wheel, on any drill/die grinder attachment and just remove the seam sealer, you can reapply with 3M 5887 EZ flexible multi purpose adhesive.
It will work just fine. It has a better flow/goes on nicer than the 3M Bare metal seam sealer and is cheaper. Tape off the lines of where your seam sealer goes, ONCE YOU LAY THE SEAM SEALER PULL THE TAPE IMMEDIATELY.. if you don't pull it off right after you lay it, it will string to tape and ruin it. It won't flow anymore (drip down..this stuff stays in place once you lay it down after a second not dries just stays in place)Use a proper gun with mixing nozzle, let out a inch of glue on a disposable piece of paper (to ensure the material has mixed properly in the mixing tube) use your finger or take a small paintbrush .5" in thickness and cut the bristles in half to make the bristles about 5/16" in length and it will make a nice straight line to make a factory seam sealer job.

Not a chance on melting it out. Its not just a normal culk/rtv stuff. You can talk to local body shops. it has to br ground out with a wire wheel and its a pita but you'll find your groove. I got plastic and tapes off everything but the roof then taped off around the valley where the seam sealer is and went to work. about 1.5hrs for each side.

Than sanded down the roof and primered/painted, The company I ordered the paint from sent the wrong color and they are refusing to work with me so my dads buddy felt so bad hes gonna repaint the roof for free lol. most shops quoted me $1200 because you have to pull off trim and stuff on the inside to "do it right"

please trust me, you cant cut/melt it out. I tried everything before I just listened and got a wire wheel and an air grinder. It went so smooth after that.

3m automix bare-metal beige seam sealer-8310. the seam sealer goes on bare untreated metal then you have to use a puddy nice and water to smooth it out then prep for paint etc. you can't use normal spray can primer. its gotta be non etching or something. I got pictures of it somewhere. its a super common issue with superduties. the two pics I have left were only haflway done grinding the old seam sealer out.
