That's also the thing I love about working on and maintaining your own vehicles .... over time you learn new little things as people watch you work. You work on this and someone comes by and suggests you do this added thing or do things in this way or that way ... they share their experience, just because they want to. You would have never learned those little things if you had gone out there to ask or interview people ... you learned them because people saw you putting in the effort to do the work.
I'm no pro but every time I worked on my vehicles, I often had a mechanic friend or acquaintance come by or someone heard that I was doing the work and they offered advice or direction without being prompted.
When you start doing this kind of work .... other knowledgeable people automatically want to jump in to help.
Keep working on it all ... you only learn more, the more you do it.
