Hi jwc, when I cover with Monokote or Ultracote on the corners or wingtips,I'll leave a couple of inches of covering to hold on to and long enough that the heat doesn't cook my fingers,generally I run the heat up to 400 to 425 degrees,the covering will really stretch nice around tips,after I have the covering shaped around the tips then I'll tack it down to the wood,I prefer Ultracote,but each to there own, covering is easy but you might practice on scrap wood to get the hang of it.
