RE: My H9 Hellcat Re-Birth
There used to be a permanent marker that was called a panel line pen. I think top flite put it out?
As to weathering you can use an airbrush, chalks, some people use the ground carbon from pencils, and rub it in.. Its really more of a diving into the water and learning thing.. there are some great weathering threads on RCU. Personally I like to do the base coat, then panel lines (on metal type planes) then I use some airbrush shading and exhaust and gun burns.. I have used just common colored chalks over that for some more shadowing. lastly I use some white chalks to highlight areas that would be on top reflecting light. I hit it with some flat clear afterwards.. I don't recall if you are running glow fuel or not? if so you need to make sure its a glow fuel proof clear.
A few of my friends that were afraid to try it are now hooked, and every plane they do looks better than the last.. The real advantage is IF you like the tough used look of warbirds..repairs are MUCH easier to hide!
