I lost two glasses on mine and then another one broke under severe cold
All of the glasses were glued using Morgan's specified glue, which is a bi composant
I was so unhappy with the issue that I went to my local body shop and discussed the matter
They used Sikaflex adhesive which requires to carefully bake the glass and mount before assembly, and then, once the two parts are bonded together, to keep these in the oven for a little while
Their views is that the adhesive used by Morgan have no chance whatsoever to work properly
I had no problem with Sikaflex for the last two years, despite some extreme cold and extreme hot conditions
