ripples, waves, bubbling appearance on t trailer

[uglybear11]

i have a travel trailer 16 feet trailer 160 sunvalley made in indiana now out of business 160 extreme is the model

it had a water leak the leak is fixed, the font panel has ripples, waves, or bubbling in a couple of places.

the construction is the fiberglass with a paper backing. then there is roll insulation with the interior paneling.

as i fixed the roof, i removed a piece of the interior paneling.... i wanted to see what was inside and this allowed air flow to allow everything to dry. i removed the wet insulation. allowed 6 weeks for a complete drying. in the area with the worst rippling, i rubbed the wet cardboard backing and some rolled up and i could see the light on the outside of the trailer.

i read an earlier post that referred to the front panel as being AF Filon? the front panel has a bend in it that goes from the front panel to the roof.

to cover the area of removed interior paneling, i made a cork board to cover the area. It is screwed to the surrounding paneling so it can be removed easily. i left it this way so i can check later on to ensure taht there is no water leak.

should i be concerned about the the front panel cracking?

i do not care about the rippled appearance ...... i am concerned about a complete failure of the front panel.... the trailer has been completely dry for 5 plus months now ...... any suggestions / warnings for the trailer?

It sounds like delamination, where the outer layer is separating from the rest. Common problem where there is/has been water intrusion. I'm sure someone here will have more specific information. You could also do a search on the topic. Hope I'm wrong...
