Best Overall: 3M Seam Sealer kit

Buy on Amazon

3M seam sealer kit is the epitome of what a great kit should be. The 3M 08620 Window-Weld 1/4" x 15' Round Ribbon Sealer Roll is excellent and it only works on non-moving glass. This roll of sealer comes with a sufficient amount of material to replace one windshield or backlite. It is great if you're setting a window because it will stick relentlessly on both the top and the glass before you start. The key is to remove all of the old bonding agent completely and really clean both the top and the glass before you start.

This package is more than enough to reseal a waterproof barrier on an SUV rear hatch. It is used to warm and insure a better bond as well. There is enough sealer to do two car doors. It only works on non-moving glass.

• Easy to apply and fairly easy to handle if careful
• Very easy to work with and provides good insulation
• Easy to work with and sealed the windshield right the first time
