Wavy fiberglass on front cap?
That is delamination and is the result of water damage. Most likely from the marker lights. Itís not impossible but an involved project to fix. My previous trailer had this issue under warranty and it was about 6 grand in labor and materials at the manufacturers rates.
However. If you can live with it and just fix the places where the water is getting in you can probably be fine just using the trailer as is.
