GM Issues Recall for Improperly Bonded Windshields
Applying Urethane
“When installing a windshield, do you lay your bead of urethane or do you apply your bead of urethane? Perhaps you are thinking, “What is the difference?” Actually, there is quite a bit of difference. I heavily favor “V” beads over round due to the better bonding and sealing dynamics. I apply the adhesive bead to either the glass or the pinchweld, depending on which type of glass part I am doing, or if there is an existing OE bead for me to follow. However, applying the bead to a surface is very important to the success of the installation.” -Bob Beranek
