Angles are not so hard. what you see are 45 degree angles which means that the sides that meet are 22 1/2 degrees. Easy enough to set up on a table saw.
I am fortunate to have a friend that does spraying so he does it for cost. I have no experience with the roll on kind but I would expect similar results. What we usually do for our mobile enclosure is a vinyl liner.
