Exactly Tom ,and also I clear the the trim with a mix consistency like water ,let it dry usually 20 min ,I use two part urethane clear ,spray it right and no polishing yaaay then cut the in 1/4 strip long way ,depending on the model some have ,one piece moldings so a large piece covers I cut thru door trim so the shadow is apparent but at first I hated foil now I'm not bad ,no pro but no rookie lol
