I've been building model kits for 40+ years and have built from every category over that time span. I remember building the BIG U.S.S. Enterprise aircraft carrier as a teenager. Also, the big 1/8 scale IROC Z28, Corvette Sting Ray, Mercedes Gullwing and Golden T Street Rod kits that came with that little package of Turtle Wax to polish the bodies with. CARS: I build 1/24 & 1/25 American muscle cars, Tom Daniel designs, and Tamiya and Revell Germany DTM and GT series with a Ferrari or Lamborghini thrown in to break up the V-8 builds. All of my car bodies are painted with Testors spray and on occasion Krylon Fusion but the Krylon takes more work to get a nice, glossy finish. Everything else is painted by hand using Testors and Tamiya paints. Everything is spray can as I don't have an airbrush. Also, due to space restrictions, I build 1/144 aircraft because I can paint them by hand and get a good result. The only drawback is that some parts are tiny and fragile and do not cooperate with large fingers. I have a Revell C-17A in 1/144 and a handful of 1/72 aircraft waiting to be built. The USN "Sundowners" and "Jolly Rogers" are my favorites aircraft markings to build. I mostly build straight from the box, detailing only with painting. This way is the most fun for me. I used to spend a lot of time super detailing with wire, solder, Verlinden detail sets and photo-etched parts but no longer have the patience to do so. I'm always trying to find ways to introduce young people to the hobby instead of playing video games all the time. I welcome and questions and/or critiques because I feel they might help me be a better builder.
