i've used trim shine on my window trim and it doesn't seem to last long. it is alcohol based i believe. Back to Black works pretty good.
Mother's Back to Black is fucking junk. It makes the trim look good for about half a week, or until it gets wet. Then it looks like shit again.
I'm also interested in a solution that doesn't require me to spend about 2 hours every weekend to keep the trim looking good. I also wouldn't mind spray painting something on the trim.
