“The only reason for those wrinkles, and they are excessive, is poor application technique. Once the patch is cut to size, and in place, you simply ensure even pressure is applied and lo and behold, a smooth surface results.”
Non professional use of speed tape suggests otherwise; there is rarely just one reason in human related activity.
Theses ‘patches’ are strips of tape, many of them; apparently with some span-wise overlap. The ‘wrinkles’ also radiate span-wise, across several strips of tape, which suggest extremely poor application or some other effect.
Not withstanding the rules and regulations of using tape, maintenance or inspection, the question at #5 relates to what exists, what is on that aircraft and is it a hazard.
Depending on scale, the wrinkles are similar to depictions of ‘runback’ icing, a significant hazard.
P.S. when applying tape - it does not tear easily or neatly, thus cut it. Before application, scissors etc, or cut with a knife through the tape down on to the paintwork !!!!
