A third day playing with a caboose. How nice. I let the robot vacuum cleaner score me some husband points. The test caboose,X1, got another interior coat of black followed by a heavy coat of white. While the paint dried, and the vacuum worked, I received inspiration on yesterday's medicine bottle failure. I found a large bottle and cut it to fit horizontally. More air gap everywhere. No more color bleed, check. Amber interior light, check. Heat tested, check. At this point I have $1.10 invested. I will make the financial leap now. I will order the parts to install LED lights in the work caboose. X1 looks pretty good on the rails. Here are today's pictures and a video showing the efforts and failures.
