RE: Heat Guns for covering
After 21 years in this hobby, I finally broke down and bought a heat gun. I have not used it yet, however. I have ironed on the vast majority of my covering jobs and simply used my Top Flite sealing iron to shrink the covering after sealing to the frame work. This has worked and was simple enough to use. Why I finally bought a heat gun, I'm unsure! I hope when I use it the first time I'll say to myself; "Self, you should have been using this along time ago"! My guess is I'll find it only marginally more useful!
What I'm saying is heat guns are not necessarily needed! Howver, this is only my opinion and I have found that my opinion and $1.25 will buy me a cup of coffee most places.
