That sounds like a good plan. Thoese three areas are the most abused spots for water spots and such. As for a glaze... if you polish correctly you dont really need a glaze. The Menzerna/gray pad will act as your glaze. Using it with a gray pad provides no cut. Its debatable weather it is worth the time/money since your not really correcrting anything, but it is suppose to help with the overall apperance.
Do not spread the 105 out like the XMT stuff, as it dries very fast. Simply spread it a tad bit and start on speed 6 right off the bat. Instead of following the 3'x3' rules I simply break the body panel up case by car. For examble I split the doors up by 4 sections and the hood by 6 sections (2 on each of the sides, one in front of the scoop, and one for the scoop).
You should be able to make about 4-5 passes with 105 before it start drying. If you feel you need more working time, spritz it with some water and do about 2-3 more passes, buff it off, and inspect. If it still have issues, hit it again. If you have issues removing it, spritz some IPA on it and buff it off.
