If I might add a little tip I've learned, don't cut your door, hood , trunk, or whatever all the way through before making you hinge. What I do is cut about 90% of the panel leaving a few little sections connected. I then make and mount my hinge, this way the panel is already aligned. Then just cut the little but that is still connected. The hinge cannot have any binding, or when you cut the panel the rest of the way through it will not align properly.
