5er trim repair.

A crack has developed along the bottom trim molding that runs the length of the bottom edge of my 5th wheel. The piece appears to plastic and seems to vibrate alot due to wind while traveling.

Can anyone suggest a good repair procedure for this. Will a fiberglass repair kit be the appropriate repair product and procedure.

Thank you all for any help or suggestions with this, the trailer is 12 years old and the manufacturer is no longer in business, so obtaining a replacement trim piece doesn't seem likely.

I'm guessing that it's that lowest edge trim panel which for all intent, hides the frame.

If it is that very thin piece of material, it will need to be supported inside once you make you repairs. While it probably isn't fiberglass but another plastic material, it can be repaired using fiberglass cloth if prepped correctly. I would, if at all possible, remove the cracked piece from the trailer - yeah, I know, a thousand screws holding that trim piece on with a lengh of aluminum with vinyl filler - but you need to clean and prep the backside with 220 to 320 grit sandpaper for a 'tooth' to hold the resin soaked 'glass cloth or matting. Once you get the piece repaired, the exterior will probably need to be painted. If you have the tools, regular auto body prep for paint will work. If you don't, rattle cans are always a good fall back with my preference being Krylon as Rustoleum is, IMO, way overrated and takes way too long to dry. OK - you've done your repair so now it's time to put that piece back on. Those many screws, a roll of butyl strip seal and the panel is back on - but you need to support it from further vibration. Some bent aluminum angle will work best - but you need it to stop flopping around in the wind so whatever works, screwed in place.
