I just started doing a build sheet for each project when done. I include the usual information about the build plus notes on lessons learned from new building techniques, materials and tools used that succeeded and failed.
I am the borderline of whether I am going to continue to watch "Fast n' Loud". It's gotten worse. My favorite automotive show is Fantom Works. The work on the cars is the main focus. Last month I was vacationing in Mexico and was flipping through the channels and found the Discovery Channel. In Mexico, "Fast n' Loud" is called the "Mechanical Duo" which is funny because Richard does not work on the cars.
