There's no gift - most people who know me tell me I should be wearing a helmet most of the time, so....
And I've ruined a ton of models in my day.
You learn from trial and error. I had a great teacher, a former USAF Ordnance guy, worked on A-26s in Korea and then went on to arm nukes aboard B-36s. He taught me early on the basics of filling seams, painting, etc. He passed away nearly 15 years ago, sadly.
The key is knowledge, patience, and equipment. Read everything you possibly can about building a model. Have your research done ahead of time, know what colors you're going to use, etc.
Patience - don't expect to finish a model in a weekend. The models you see here are anywhere from 35 hours to 300 hundred hours.
Understand each and every aspect of the construction before you glue. Kinda like measure twice - cut once. The biggest mistake modelers make is wanting to see the model finished - and they rush it as a result. That's when mistakes happen.
Tools. It doesn't take $10000 worth of tools to make a beautiful model. But having the right stuff to do the job helps. No one uses the old toluene tube glue anymore. Everyone uses CA (superglue) and MEK (Methyl Eythl Ketone) based products like Tenax 7-R, Ambroid Pro-Weld, and Tamiya Thin Liquid Cement. These reduce your build time from hours (waiting for stuff to dry) to seconds in some instances.
You also have to develop techniques and get into habits that are otherwise boring. Don't wait to clean the airbrush - do it immediately. Never pull parts from the sprues, cut with nippers or use a razor saw. Test fit everything before you glue it, etc.
Painting is an exercise in patience, but there are tricks. If you use a spray can, shake the hell out of it, then put it into a pot of hot water. Let it sit for a few minutes. This increases the pressure in the can and improves atomization of the paint. Paint a part, a fuselage, wing, or entire plane, then put it away. Schedule your painting that it happens at the end of a building shift. This allows the model to dry overnight while you're off sleeping or playing AH. When you come back to it 24 hours later, the paint is hardened and you can continue on.
If anyone is a modeler, and wants help, please don't hesitate to ask. Unlike learning how to master E in a 109, I have no trade secrets. I'll gladly share what I know.
