What I do is sand the entire tube down as much as possible. Then, I paint it with Kilz
primer. I roll it on, or you buy it in spray cans. After the Kilz, I wet sand the entire
tube. I do this outside with a water sprayer to keep it wet. The water keeps the sandpaper
from clogging up.
I build large rockets 7.5" diameter and up, so I can't afford enough spray paint, nor can I
afford auto paint. I simply roll on Rustoleum oil based enamel. A quart will do a 7.5"
diameter 12 foot tall rocket several times.
Someone suggested more epoxy on the tube, but that will certainly add weight.
