Mothers Back-to-Black Trim and Plastic Restorer

Owners broadly report 4-8 weeks on a daily driver washed regularly, with some long-term users on forums noting monthly reapplication as their routine. The manufacturer does not specify a durability window on the label; the community midpoint sits around 6 weeks under normal wash frequency.

The finish character is satin to low-gloss, not high-shine or wet-look. Owners generally describe it as appropriate for black exterior plastic trim -- it restores the darkened appearance without the tacky or greasy feel associated with older silicone spray formats. Apply a thin coat and buff off any excess for the cleanest result.

Because it is wiped on by hand, the real risk is the liquid smearing or dripping onto adjacent panels rather than airborne overspray. Owners in forums note that product left on painted surfaces can leave a residue that requires removal, but no permanent paint damage is documented under normal application. Use a foam applicator to keep product off painted panels, or mask adjacent painted surfaces on close-tolerance trim. The bottle's CAUTION label now reads 'Possible Eye or Skin Irritant.'

The label lists plastic trim, rubber seals, and vinyl. Owners confirm effective use on ABS exterior trim, EPDM rubber door seals, and textured bumper cladding. Back-to-Black is not intended for painted surfaces, glass, or interior plastics -- those require category-specific products.

The SDS carries a WARNING signal word with H315 (skin irritation) and H319 (eye irritation) -- standard for liquid exterior dressings with surfactant chemistry. The SDS explicitly states no Proposition 65 chemicals are present. The trade-secret formula (85% of ingredients) limits full chemistry verification; the preservative system is not disclosed. Nitrile gloves and safety glasses are appropriate precautions per the GHS classification.
