Sprayon SP603 12oz Blue Layout Dye

Sprayon SP603 Blue Layout Dye provides a fast, even coating for precise scribing and layout work on metal, aluminum, or glass. This 12 oz net-content aerosol lays down a dark blue, non-glaring film that dries almost instantly and resists rubbing off, flaking, or peeling during marking and machining. The uniform color creates sharp contrast so mechanics, toolmakers, and machinists can see fine lines clearly when transferring patterns, checking hole locations, or setting up tooling. Because it’s non-etching and non-staining, SP603 supports accurate inspection without affecting the surface, and it removes cleanly with Sprayon SP606 Layout Dye Remover when the job is complete.

Designed for pattern-making, tool and die work, and general maintenance machining, SP603 helps reduce rework by improving line visibility and consistency. The aerosol format reaches irregular shapes and edges, and the quick-dry film stands up to handling during measurement, center punching, and cutting operations. Keep a can at the layout bench, mill, lathe, or inspection station for reliable, repeatable results across parts and fixtures.
