Why not? Factory stock would be a category that I would hope they understand the subject matter, but not every judge is an expert in every make/model of car/truck. Replica stock, again, the judges may have no knowledge of the subject at hand. Also, Lets say for example, you had one rim you liked but not a set, and you cast the rest of them, or one seat a cast and duplicate, or that you scratch built certain parts, how would they know that unless you told them? Having said that, a judge does not need to know anything about certain makes/models to understand that someone left a mold seem where one would never ever be, or that one paint job is better than another. I see really shiny paint jobs win paint awards, but to me, they are WAY way too scale thick. doing extra work for the sake of doing extra does not mean a finished model is better. Yeah, someone opened the doors, but if they hacked them up, and they do not fit or look right????
Aside from that, it is not always just the judge that is reading it. The spectators may want to know more, such how long did it take, what kits did you bash, "oh this dude cast his own wheels!" and so on. Much like looking at the i"n progress" builds on this forum....I do not only want to look at the under glass category. Tell me more! LOL
