The Ford F1 (1948–1952) is the original Bonus Built pickup — every surviving example is now more than 70 years old, with original or restored enamel and lacquer paint, chromed steel bumpers and grille bars, and a high-profile separate-fender silhouette that no modern truck cover pattern addresses directly. Standard covers sized for contemporary flat-body trucks pull across the F1's proud fender peaks and create tension at the running board edges, producing paint contact on every removal cycle.

DaShield's Ultimum is a multi-layer woven cover with a soft inner face engineered for high-profile collector trucks. The woven construction allows moisture vapor to pass through rather than condensing against the F1's chromed surfaces during overnight storage. The soft inner face lifts away from the original or restored enamel without transferring abrasive particles to the paint surface on removal. For show-quality F1s in active use or long-term storage, the Ultimum provides the construction depth that a 70-year-old truck with irreplaceable paint requires.

Designed in Buena Park, California. Available in Ultimum (Lifetime), Vanguard UHD (5yr), Vanguard HD (2yr), and SoftTec Satin for enclosed indoor storage.

Most truck covers on the market are patterned to modern flush-body pickups. The Ford F1's separate fenders, running boards, and flat windshield create a high-profile geometry that sits differently under a cover — the fender peaks stand proud of the body surface, and the running boards add a lateral protrusion at mid-body that the cover's side panels must clear without bunching or pulling taut.

DaShield fit specifications for the F1 account for this high-profile geometry. The cover's drop length is sized to drape past the fender peaks without tension across their tops, and the side panel dimensions accommodate the running board protrusion without the lateral pull that creates contact pressure at the lower fender body.

The Ultimum's multi-layer woven construction addresses the F1's two primary storage vulnerabilities. First, the woven layer structure allows moisture vapor to pass through rather than condensing against the truck's chromed bumpers and grille — the wet-dry cycling that pools beneath non-woven covers is the primary driver of chrome pitting on postwar steel. Second, the soft inner face does not shed abrasive particles onto the enamel or lacquer surface during removal, which matters on a paint system that has no sacrificial clearcoat layer to absorb micro-contact damage.

The F1's enamel and lacquer paint carries no separate clearcoat to absorb UV degradation before the color layer is affected. NOAA-documented UV accumulation in high-index regions degrades organic coatings progressively, and a cover that meets AATCC 16 colorfastness standards intercepts that radiation before it reaches the paint. Non-woven polypropylene covers do not meet this standard consistently and offer no moisture vapor transmission for chrome surfaces.

Multi-layer woven construction. Soft inner face. AATCC 16 UV resistance standard. Wipe-down maintenance only — no machine washing required. Lifetime warranty on the Ultimum. 5-year warranty on the Vanguard UHD. Sized to the F1's standard single-cab, full-bed, high-profile body.
