I was able to spend quite a bit of time on the track this weekend. I manged to get 95% of the screen down and about that much plastered. Looks like a blizzard hit the track LOL.
It does define the track a bit better now and there are no major canyon of doom areas.
I used craft plaster strips along the facia and track for a clean edge and to allow me to staple the screen to the side of the roadbed and not on top of it like last time. I had several areas where I got almost 1/2" of track back.
I've got 15 lbs of Sculptamold left, so that is the next step to fill in all the open areas. It does define the track a bit better now and there are no major canyon of doom areas.
