Thanks for the kind words all.
Spurkey,
Looking closely at my boosters with the naked eye, a slight weave pattern is visible. I filled a few small areas with Spot Bondo where there was actual pitting, but did not take the steps necessary to remove any signs of texture.
Part of what reduces the visibility of the texture is the multiple build ups of paint. For the white base coat, I did two light coats of primer and then over three days 2-4 coats each day of Krylon Gloss White. That covers a lot of tiny surface imperfections.
Spot Bondo is good for small areas but gets messy for more than that. Wiping on more epoxy can fill surface texture, but adds weight.
A technique that has worked well for me on other projects is to brush on coats of latex primer. Two+ days later, sand it until you just start to see the underlying surface. Then spray prime and spray paint.
The latex goes on very thick compared to spray paint and fills a lot of small blemishes. It also weights and costs less than epoxy. I have done this twice on other projects and been very happy with the result. One was my L2 project, a modified Sirius Rocketry Saturn V, details on bpasa.com and TRF.
I will have a Boostervision (video) Gearcam taped to the rocket on the side facing away from spectator view, and also shoot DSLR stills and HD video from the ground. Flight details, pictures and video will be posted.
