I am tracking that a few RV-10's have had issues with windows separating in flight as a result of the Lord adhesive that was once used. Now it looks like Van's recommend Weld On #10 to install the windows. However, on the RV-14A we used Sika Flex with great success. Curious your opinions on Weld On #10 vs Sika Flex or something else to install the RV-10 side windows.
