yesterday I was looking at the county (St Joe IN) fair rockets. Besides the weird paint choices, like a florescent orange Citation Patriot, with the decals. Orange without them would be fine. Most had very well sealed fins little grain showing here's the weird part: there was hand written sign saying the rockets were flow in late April and then painted for the fair. Thirty years ago I was flying in a local park and a slightly younger person told me that you had to fly your rocket before you painted it. Something about the paint would not go on correctly. Having already, at that point, done over 50 models, I knew it was BS. As far as I know that kid years ago could be to local 4-H rocket guy now. Where would this idea come from? Has anyone else heard it? Is there a line in the Estes instructions that I have missed in the last 40 years? Do you paint right after the flight so the tube is still warm?
