I'm using a green transparent covering on a 90" glider. The first piece I put on finished really clear. The second piece has a rippled look on the glue side and seems to show the glue in the open spaces between the ribs. I sealed the ends with an iron and used a blower on the majority of the wing. Did I not get the second piece hot enough, or did I get it too hot? Any Ideas?

Thanks,

Randy
