HOW TO: Create an Invisible Seam Sealer on GM Vehicles

HOW TO: Create an Invisible Seam Sealer on GM Vehicles Ryan Marrinan, 3M Application Engineer, talks about seam sealer replication, particularly on GM vehicles, and how to replicate something that wasn't there from the factory. Step 1: Prep your panel (00:42) Get your panel prepped, and use epoxy primer if there’s any bare metal exposed. Taping off the region isn’t as crucial for this bead, but it helps to keep slop from laying around. Step 2: Prep your seam sealer (00:57) We’re using our 3M™ EZ Sand Multi Surface Repair Material 05887 for this application. As always, equalize it first in an upright position into a paper towel, making sure equal parts A and B are being dispensed. Once it’s equalized and the tip is applied, tighten down the lock ring and dispense some material onto a mixing board or paper towel. You want to make sure the material is thoroughly mixed. For this application you’ll want to turn down the air pressure on the applicator a little bit. Step 3: Lay the material (01:44) As you apply, maintain an inward angle to force the material into the hem flange, making sure to create a tight seal. Then come back with a spreader and work it in. Use a lot of downward pressure and use your finger on the backside to create a scraping effect. You’re trying to force the material into the seam, then you want to scrape the material off. If there’s too much, go back and clean up the top edge while the tape is still attached. Pro tip: Start and stop from the same position When doing this type of application on replacement panels, door skins, deck lids or hoods, make sure to always start and stop from the same position. Start at one point and work your way around the length of the entire panel, then go back to the same point to start with the spreader. Step 4: Remove the tape (03:18) Pull the tape off, and as always with our seam sealers, best practice is to pull the tape back against itself, creating a nice clean cut edge. Do that each and every time and it becomes natural. Step 5: Clean up any excess (03:39) If there’s material on the panel that you don’t want, you can remove it with either our 3M™ Specialty Adhesive Remover 38987 or our 3M™ General Purpose Adhesive Cleaner 08984. Wet it out on a towel and wipe up any excess while the material is still in its working condition and not yet cured. If you need to get close to the application, create a nice sharp corner with the paper towel so you don’t get into the bead and have to redo it. Step 6: Finish the corner (05:02) If you have a little bit of the corner left, come in with some material and take the spreader and work it in really tight again. If it’s an awkward corner and the spreader doesn’t fit, you can use a protective glove and clean up the edge. Now you’re ready to go. When you send this off to paint it’s going to create a nice tight seam-sealed edge, but give you that factory look. Important note: There are of course many factors and variables that can affect an individual repair, so the technician and repair facility need to evaluate each specific application and repair process, including relevant vehicle, part and OEM guidelines, and determine what is appropriate for that repair.
