AHHHHHHHHHHH!!!!!!!! My horrible drawing still lives.
Good thing I make my living doing anything besides drawing.
If you are going to glue it down, a couple other little things will help make it work AND look good. First, make sure you clean the glass and the underside of the trim in the area to be glued down. Use a good glass cleaner, spray the hell out of the area under the trim. Then take a couple paper towels folded 4-6 layers thick so you have a nice pad, slide between the glass and the trim, then carefully push down on the trim and slide the towel back and forth several times cleaning the glass and the back of the trim. When you apply the urethane, put enough of a dab so that it squeezes out a
little when you push the trim into place. Then, clean off the excess with enamel reducer (which is the only solvent I am aware of that effectively cleans urethane), and tape down to the glass for atleast 6 hours. I wouldn't put tape onto the body unless you can't get it secured well by taping to the glass only. You'd hate to find out you have paint adhesion issues the hard way. At the same time though, you want to be sure to hold it into place until the urethane dries. Lastly, if you can't get ahold of any reducer (most FLAPS have it in 1 qt cans), you can use less urethane so it just barely squeezes out, and trim that off with a razor blade after it dries, but the final appreance can be unpredictable.
