Review on 🔍 3M Self-Leveling Seam Sealer 08307: Quick-Curing Epoxy for Seamless Joints - 200 mL/6.75 fl oz Cartridge by Michael Heidelberg

Bought as a replacement for the seam sealer on Chevy 71 pickup drippers. Make sure you level the car - tape off the areas you don't want this stuff on and REMOVE the tape that way as soon as possible before it hardens, otherwise it will stay there forever (and trying to peel it off from under the seal will cause the seal to expand because it's good). You can't use this on vertical sections as it will flow for at least five minutes before it starts to settle. I ended up buying a dense body seam sealer (3M 8303) to do the vertical sections first (along with a few spots on the firewall and hood) and then use 08307 for the flat areas (smooth glass). Wear gloves - it's messy if you're not careful.
