Lithium Auto Elixirs Trim Serum is a concentrated 16 oz black plastic restorer that revitalizes faded plastic, rubber, and vinyl, penetrating pores to return deep, lasting color for months.
Trim Serum is formulated to bring neglected exterior trim back to a factory-black look without greasy residue or complicated steps. Designed for cars, trucks, SUVs, and motorcycles, the formula soaks into weathered surfaces to replenish color, add UV protection, and reduce future cracking and oxidation. It’s made in small batches from premium polymers and conditioners to ensure consistent performance and long-lasting results.
Visible transformation happens within seconds: faded, gray trim darkens to a deep black as the serum penetrates the surface. Full drying takes a few minutes depending on temperature, leaving a clean, non-oily finish that holds up through daily use.
Trim Serum was created for exterior automotive plastics, rubber moldings, bumpers, door surrounds, mirror housings, and vinyl accents. It’s ideal for reversing UV bleaching, oxidation, and the dulling that comes with age, without altering texture or gloss dramatically.
The formula contains UV inhibitors and durable polymers that form an invisible protective layer, so the restored color lasts for months under typical weather conditions. Longevity depends on climate, washing frequency, and exposure to intense sun or chemicals.
Application is simple and low-mess: apply a few drops onto a microfiber applicator or cloth, spread evenly, and buff off excess. There’s no need for sanding or primers—just clean the surface first and work in small sections for uniform coverage.
Who is this for? Trim Serum is for car owners, detailers, and restoration hobbyists who want fast, reliable trim revival without complex prep or messy application. If you own a vehicle with faded bumpers, dull mirror housings, door seals, or rubber moldings and prefer a subtle factory-black restoration that lasts, this product delivers professional-grade results in a user-friendly form. Backed by Lithium Auto Elixirs’ small-batch formulation approach and warranty, it’s a convenient solution for anyone seeking to upgrade curb appeal and protect exterior trim from further weather-related deterioration.
