Finishing rockets isn't exactly my forte, I'm more of a making-motors kind of guy...
Recently I bought a water-damaged Interceptor G kit. Fixed the slightly-warped fins, replaced one body tube. It's lovely; got a coat of flat white primer right now. The decals are self-stick and appear to be mostly in good shape, but there are a few places where they've separated from the backing and a little dirt got onto the adhesive. Advice? Best regards, Terry
