Fiberglass issues

[Cngdad]

I have a Surveyor SV291 TT. It is a 2004. I had a leak in a front marker light and around the front window that I call a waste. At any rate I have noticed some slight bubbling of the fiberglass around the upper corner of the front window. I see it more when it is extremely hot out. Does anyone know if this should be a concern or should I just monitor it to see if it gets worse?

I assume you have located the source of the water leak and sealed it already. Water inside a laminated wall will remain there until the wall is opened enough for the water to evaporate. Depending on how much you value the trailer, I would remove the window (inside a garage is best) and expose the wall edges so at least some water could evaporate. Once you feel the wall interior is dry, you may find some tips and advice for repairing the "bubbles" in the wall at this website.
