That is really nice. I don't know if this will help or not but I've put the glass in place and held it in place with painters tape. Then use the clear glue in a few key spots that wouldn't be noticeable.
I don't go to HL anymore because I liked being able to buy what I wanted with the 40% off coupon. I have all the kits they have. And I didn't see the Molotow chrome pens the last time I went.
Is there a way you can place a low table in front of the window and run it straight out? I don't have the Pace but this is how mine is set up. You could always move it away from the window when not in use. Just a thought.
