PPG Deft 03-GY-308 Gloss Gray MIL-PRF-85285E Topcoat – Gallon Kit for Military Aviation
PPG Aerospace Deft 03-GY-308 is a gloss gray (FS#16081) MIL-PRF-85285E Type I, Class H aerospace polyurethane topcoat — the high-gloss variant of the Deft military gray topcoat range, used on military aircraft and aerospace systems where a gloss rather than flat gray finish is specified. FS#16081 is a Federal Standard 595 high-gloss gray color designation used on specific aircraft, engine components, and military equipment where the specification calls for a polished, high-gloss gray appearance rather than the matte tactical flat gray used on exterior aircraft skin surfaces.
Gloss gray topcoats are used on military aircraft components, engine nacelles, interior equipment, ground support equipment (GSE), and specific airframe areas where the applicable technical order requires the gloss finish variant. The high-gloss surface provides a clean, bright appearance that aids visual inspection of the coated surface condition and facilitates cleaning of fuel, hydraulic fluid, and other fluid contamination from the component surface during maintenance.
The gallon kit provides the standard production quantity for military painting operations, with the high-gloss aliphatic polyurethane chemistry providing the outstanding UV stability and appearance retention needed to maintain the FS#16081 gloss gray specification through extended service.

Technical Information
Deft 03-GY-308 uses the same aliphatic polyurethane chemistry as other MIL-PRF-85285E Deft topcoats, but the formulation omits the matting agent used in flat/matte variants, producing a high-gloss film from the inherently smooth polyurethane surface formed during cure. The 60-degree or 85-degree gloss level of FS#16081 gloss gray falls in the high-gloss range of the MIL-PRF-85285E specification, providing the bright, reflective appearance characteristic of gloss-finish military equipment.
Achieving the specified gloss level in the cured coating requires correct application technique — proper spray distance, material pressure, and overlap pattern produce a smooth wet film that levels to a high-gloss surface during cure. Incorrect application technique — excessive spray distance, incorrect pressure, or insufficient film wet-out — can result in lower-than-specified gloss due to orange peel, dry spray, or uneven film formation.
The FS#16081 color standard uses a gray formulation in the Federal Standard 595 gloss tier — distinct from the flat gray FS#36xxx series. Always verify the correct FS code, gloss level, and color specification for the component being painted against the applicable technical order before applying the coating.

Frequently Asked Questions
Q: What is PPG Deft 03-GY-308?
A: 03-GY-308 is a gloss gray FS#16081 MIL-PRF-85285E qualified aerospace polyurethane topcoat for military aircraft components, equipment, and surfaces requiring a high-gloss gray finish.
Q: MPN for Deft 03-GY-308 gallon?
A: MPN is B800G308XZG222K.
Q: What is the difference between gloss gray and flat gray topcoats?
A: Gloss gray (FS#16xxx series) has a high-reflective finish. Flat gray (FS#36xxx series) has a matte, non-reflective finish. The choice depends on the specific FS code required by the aircraft’s technical order for each surface area.
Q: Where is gloss gray used on military aircraft?
A: Gloss gray is used on engine nacelles, interior compartments, ground support equipment, and specific component surfaces where a high-gloss finish is specified — as opposed to flat gray used on external tactical surfaces.
Q: Is there a difference in performance between gloss and flat Deft topcoats?
A: Both use the same MIL-PRF-85285E chemistry. The primary difference is gloss level — gloss coatings lack the matting agent, producing a reflective surface. Performance properties (UV resistance, chemical resistance, flexibility) are similar.
