Product Guides & Tutorials

Step-by-step instructions to use your STEDI tools safely and professionally.

How do I use STEDI nippers to cut model parts without damaging the plastic?

First Cut (Rough Cut)：Hold the nipper to the sprue, leaving 1-2mm of plastic on the part to avoid stress marks.
Second Cut (Flush Cut)：Make a second, slow cut as close to the part as possible to remove the remaining sprue nub.
Finishing Touch：Use STEDI sanding sticks or files to smooth any leftover nub for a seamless finish.
Pro Tip：Always cut away from your body, and after each use keep nipper blades with Rust-preventive oil to prevent rust.

What’s the best way to sand and finish model parts for a professional paint job?

Start with Coarse Grit：Use 400-600 grit STEDI sanding sticks to remove nubs, scratches, and mold lines.
Progress to Finer Grits：Move up to 800, 1200, and 1500 grit to smooth the surface, always sanding in one direction to avoid cross-scratches.
Final Polish：Use a 10000 grit polishing file for a mirror-smooth finish, perfect for primer and paint adhesion.
Pro Tip：Use STEDI sanding sticks or sandingpaper to get into tight corners and curved surfaces.
