Here is my idea to this topic.  There is a lot of really good information in this forum, but it is scattered all over the place.   For example, there are great post about putty, primers, and other such things, but not all in one location.  (Yes I know that these are in the painting thread, but not easy to find, especially if you are a beginner, and new to the forum.) 

It would be great if all of this information was in one easy to find place.
