I waited for it to dry on all my emblems and GMC emblem on the front but I also taped off and left a gap like everyone does. That worked great, but on the window trim I taped them off right against the chrome on the top because there isn't much of a line or anything for the dip to cut itself cleanly. If in situations where you tape it off real close to your line or can, its best to peel tape when its wet. It came off clean as a whistle, I've done it both ways just on the trim this worked alot better.
I also only waited about 5-6 minutes in between coats this time with the trim, where as before I waited about 10 minutes or more between coats, so i'm sure some of your coats before were pretty well dry so that made a difference in it not coming off clean.
