Field notes
The site separates process knowledge from materials research: guides cover preparation, masking, airbrushing, cleaning, and finishing, while the paint index supports comparisons by manufacturer, color order, chemistry, and finish. The homepage names six paint makers and describes a separate stash tracker that accepts kit barcodes and keeps collection data on the user’s device. Recent entries indicate active additions, including a September 2026 masking-tape guide.
