How to reinsert the ceiling panels' plastic joint trim?
The trailer had a rain leak from a newly installed(improperly) vent. I first sealed the vent topside with sufficient Dicor lap sealant. Then, to clean the stains and to dry it out, I removed the trim from the bottom of the vent. The ceiling panels join at the vent and unfortunately, a stain also extended along the plastic joint trim between two ceiling panels and over to one wall. I removed this trim piece by easily sliding it out at the vent opening. Once cleaned and dried, it doesn't seem possible to reinsert the trim piece. Do you know a proper way to do this?
