I use the windex method with a twist. Once the trim piece is down in place, you can use a credit card, or something made of hard plastic like that, to squigee out the excess windex. Let dry for about 24 hours. Then, useing a fine detail type paint brush, use trim solvent, and just paint a thin line around the edge of your trim pieces. The color in monokote, is in the adheasive, so you do not need much. Some will most likely bleed out if you are putting a dark color on top of a light color, don't worry about it. Let it dry for about 24 hours then put a small amount of the solvent on a clean cloth to clean off any that bleeds. Your done. I read about this technique here on rc universe, and have tried it on 2 planes and have not had a problem with any seperation. I have run about 6 or 7 gal. of fuel thru one of them. BTW there is no need to poke holes in your base covering, and there will be no air bubbles. One more little hint is if you need to touch up something small you can use the paint brush and solvent, swirl the brush around on a scrap piece of monokote the right color and voila instant matching touch up paint. Good luck, happy flying. Garry
