I love to read for one thing. I prefer holding a book rather than reading it on a screen, although I've learned a lot from this forum.
Having a hard copy from an expert would inspire me to try things that I now shy away from due to lack of confidence, and not having a handy reference available.
I might even share with my son-in-law, who still uses Turtle wax, and was a little jealous of how much better his Equinox looked when I did it as opposed to when he does it.
