U-Pol UP0791V HIGH #5 High-Build Gray Primer Aerosol 450ml

The U-Pol HIGH #5 (UP0791V) is a professional-grade high-build lacquer primer in a convenient 450ml aerosol can. Formulated to fill and level uneven surfaces prior to topcoating, this gray primer delivers spray-gun-quality results without the need for mixing, cleanup, or specialized equipment — making it an ideal solution for both professional body shops and serious DIYers.

Designed for spot repairs and panel prep, HIGH #5 adheres to a wide range of substrates including fully cured paint, polyester body fillers, GRP (glass-reinforced plastic/fiberglass), and properly prepared steel, aluminum, and galvanized panels. Its fast-drying, chromate-free formula sands easily and provides excellent coverage of up to 21.5 sq ft per can, with a dry curing time of approximately 60 minutes.
