Falcon161, congrats! - For modeling, here are a couple I suggestion:
Before painting by can or airbrush, wash your model with dish detergent to remove oils from the mold release agent/fingers, etc.
Test fit before gluing
Warped part? - Run under hot water for a little bit, and rebend to original shape
Use a glue that welds like tenax7 for a better bond
Gun Residue from firing? - If you have access to a black pastel chalk, ground a little & dust onto the model with a paint brush from cannon port to the back of the plane (not too long)-remember wind effects
Want your panel lines to stand out after painting? -Use a pen with india ink from any art supply store or a simple .5mm mechanical lead pencil, but make sure the lead is soft (dark)
With a "gear down" look and tires bulging from weight - Heat an old screwdriver tip or butterknife and press your wheels down slightly
Don't use super glue for cockpit windows- Scratches in windows can be rubbed out with toothpaste (not the gel kind)
Atoll nose? - Cut a 1/8th" tip off a bic pen and graft onto the missile head
Oxygen hose for your pilot? - carefully break an old burnt out bulb, carefully retrieve/clean the filament, dip in black paint, and voila - oxygen hose (may not be scale), but it looks good.
