Everything I do requires a lot of sanding (which is why I skip the paint sometimes). Heavy coats of primer on the difficult spots is one way. I've also used a very light body filler from an automotive paint supply shop, pretty easy to sand, but still a lot of work to get a really good surface for painting.

But my suggestion is even easier: Build bigger rockets, so that everyone views them from much further away, and doesn't notice things like pinholes and un-filled glass weave. - Rick "Go big or go home" Dickinson -- ROC-Chat mailing list roc-chat@xxxxxxxxxxxxx //www.freelists.org/list/roc-chat
