How to re-glue interior panels?

[Gary Roe]

I use Dicor 501LSW Self-Leveling Lap Sealant. This stuff is great for sealing your RV's roof seams and penetrations. It sticks like crazy and flows into all the nooks and crannies. Beware: If you get it on yourself you have to mechanically remove it, if you get it on your clothes, you'll never get it off. Get plenty: I used 1-2 tubes per roof vent and 2-3 per full-width seam, so a full dozen was just the right amount for a 31' RV's three roof vents, two sanitary vents, two seams, and other various roof penetrations. Don't bother with silicone or any other sealant - they won't stick to your roof and they will leak in a couple of months.
