Beautiful work - the glass is coming alive again for sure, especially with the reds!

It would seem that the glass has not yet had any Triple Thick applied, as you are scraping paint away.  I presume you may be going to seal it after?  The reason I ask is that in some cases it would appear that sealing is the first thing to do (eg. what Nino recently did for the Buccaneer), and in other cases the sealing may need to come after.

It probably depends exactly on what is needed for the restoration of the backglass.
