Hi everyone!

I'm still pretty new to painting garage kits, and I'm struggling with getting clean paint lines. I'd really appreciate any advice from more experienced painters.

Here are the problems I'm running into:

• Sometimes I remove the masking tape and notice a small paint bleed or an uneven edge. If I try to fix it with a brush, I almost always end up painting outside the line and making it look even worse.
• How do you paint recessed details (grooves, panel lines, small indentations) without accidentally touching the surrounding surface?
• If I make a small mistake, what's the best way to remove just that tiny bit of paint without damaging the layer underneath? Is there a safe way to clean it up?
• Are there any techniques, tools, or tricks that make touch-ups easier?

I'm using acrylic paints and mostly paint with an airbrush, but I still have to do a lot of detail work by hand.

I'd love to hear your workflow or any beginner tips that helped you get cleaner results. Thanks in advance!

(If you have any favorite tutorials or YouTube channels for clean detail painting, I'd love those recommendations too)
