    303 Marine Aerospace Protectant 30370CASE supplies four separate 1 gallon containers for matte protective care of suitable clean, dry materials. Mariners Warehouse SKU 78280 is the full case purchase. Compare the complete quantity, expected use and storage before ordering; it is not a single oversized container.

    Manufacturer examples include vinyl, rubber, plastics, finished leather and other specifically permitted surfaces. Current exclusions include clear plastics, unfinished leather such as suede, fabrics or canvas, flooring, gauge panels and headlights. Clear-vinyl panels need their dedicated care product, and a broad marine label does not approve every cabin material or traction area.

    Prepare a clean, dry permitted surface and use a drop cloth to catch overspray. Work out of direct sunlight, spray onto the surface or a clean microfiber towel as directed, and wipe thoroughly dry. If excess causes streaks, remove it with a damp towel and buff dry. The formula does not air dry; complete removal and inspect rather than leaving a wet coating behind.

    VINYL & RUBBER CARE GUIDE

    Six Steps to Protect Suitable Clean Marine Surfaces

    Match code 30370CASE, the package and the exact surface before starting. These six checks keep the marine vinyl and rubber UV protectant routine tied to the right material, preparation and finishing method.

    1. Confirm Material and Case Quantity

      This order supplies 4 separate 1 gallon containers. Match the formula to the surface and keep original directions with every container distributed.

    2. Exclude Unsuitable Surfaces

      Keep it off clear plastics, fabric/canvas, flooring, unfinished leather, gauge panels and headlights.

    3. Clean Before Protecting

      Remove soil with an appropriate cleaner and prepare the surface as the label requires.

    4. Apply Out of Direct Sun

      Protect nearby areas and apply to the approved surface or microfiber towel as directed.

    5. Wipe Completely Dry

      Buff to a dry finish. If excess causes streaking, remove it with a damp towel and dry again.

    6. Plan Repeat Protective Care

      Inspect after exposure and follow label guidance; the manufacturer marine page recommends 3–5-week reapplication.

    Case Quantity and Material Protection

    This 30370CASE listing supplies four separate 1 gallon containers. The individual-container alternative is a separate purchase. Compare total supply, storage and current unit cost; case quantity does not change the underlying formula’s material approval or working method.

    Choose Aerospace Protectant for matte care on clean, dry permitted materials. Clear plastics, unfinished leather, fabrics/canvas, flooring, gauge panels and headlights remain excluded. Fabric Guard and Clear Vinyl Protective Cleaner are different products for different materials. Review the 303 Marine Aerospace Protectant - 1 Gallon MPN - 30370 as a separately sold option.
