well on my first dash fab, i used Duramix 4040 to structure the screen housing in place, then i used Rage gold (filler) for the skin coat. After a couple months i could see a crack starting to happen.
if you look in my video near the end right around 51 seconds left you can see it
Im redoing the dash soon since i am rebuilding the carputer. I will be switching from a lilli 619(fried now) to a xenarc w/ video inputs. I will use the 4040 to hold screen in place then use 4058 for the skin coat and sand my *** off then on
