My first covering job left a lot to be desired, but looked ok for a beginer, however after just one trip to the field and a few weeks living in the ever hotter south Texas garage it has began to sag alot. No problem, break out the heat gun right? Thing is, decals are all around some of these loose spots and I don't know how to avoid messing them up. Would a cool wet cloth keep them safe or am I just S.O.L. on the decals? (Yet another thing that plane has taught me!)
