This is the body tube from an Estes Honest John I purchased a few weeks ago. The packaging is stamped 2015. Question 1: Do you see spirals? Q2: Would you apply putty, wood filler or Bondo to fill the spirals? Q3: Do you think sandable primer is sufficient? Q4: How about just a little sanding and regular primer? Q5: How WOULD you prepare this tube? Q6: Why aren’t all tubes this smooth? Q7: Is this a sign of things to come? Did Estes recently find a way to make tubes with negligible spirals? I had reached a point where I was looking forward to trying out new spiral filling techniques. But now I see this and I’m stumped.
