All the difficult and time-consuming rocket construction steps are basically complete. The drilling and sanding fiberglass is done, the epoxy has cured, and technically, you can fly it “naked” at this point. But a painted rocket just adds that extra touch of class, and we are nothing if not classy.
Before getting started here, a couple of tips and some basic prep. There are a few parts that you might want to cover before spraying anything: things like the aluminum tip on the nose cone, the aluminum motor retainer, and the rail buttons. You can use masking tape to manually cover up these things pretty easily.
Also, keep in mind that where a coupler slides into another section of the airframe with a snug fit, you don’t want to build up multiple layers of primer and paint, or things won’t fit at all anymore, without sanding the paint off. You may want to cover coupler ends with masking tape as well to save yourself trouble later.
So, to begin: lay out the rocket on cardboard or somewhere that you don’t mind getting turned into a rainbow of colors. Spray a thin layer of primer over everything (I chose a simple white primer) and use a quick back and forth motion. Don’t spray too close, and keep it continually moving while spraying, so that paint doesn’t build up too much in any single area. You can always come back and spray again and again, lightly with a thin coat each time.
Of course, since the parts are lying on the ground, you can’t get underneath and will need to wait for them to dry and then rotate them. Depending on how much you’re able to coat the pieces each time, you may need to rotate them just once, or perhaps twice.
Finally, once everything has a nice layer of primer and it’s dry, you can begin spraying paint. The colors and design are totally up to you, but I would certainly recommend a high gloss finish.
In my case, I went with a glossy navy blue for the rocket body. I then used “sunshine yellow,” also glossy, for the fins and the vent ring around the e-bay. Note that it didn’t matter if the layers of navy blue got all over the fins, but once this was finished, I had to use more masking tape to very carefully and thoroughly mark off the fins from the rest of the body. I also used some brown paper grocery bags, tearing them up into approximate sizes to cover the rocket between and around the fins, with masking tape at the edges sealing it off to create sharp and exact lines.
I’m no expert painter; this is only the second rocket I’ve ever painted. But I think once finished, it turned out pretty well.
Of course, this paint job is bound to get scratched, scuffed, and generally deteriorate over time. The rocket gets disassembled and re-assembled, and parts bump and bang into each other, and of course upon landing after even a single flight it will get dirty and a bit dinged, no doubt. I can always touch up the paint in the future when that happens, and it doesn’t really matter – it’s purely cosmetic. But it is fun and it just completes the look.
