L-688 2K Super White Acrylic Automotive Paint High Gloss Coating for Car Body Refinishing Repair
L-688 is a two-component (2K) acrylic automotive paint engineered to deliver a deep, bright super white finish for professional car refinishing and repair. Once mixed with its dedicated hardener and thinner, it cures to a hard, high-gloss film with strong hiding power and a clean, long-lasting white color.
Built for spot repair, panel respray and full-body repainting, L-688 delivers a smooth, even coating film with excellent adhesion and weather resistance, making it suitable for a wide range of solid white refinish jobs.
Sharing the 2K super white concept but formulated with different raw materials, L-688 offers a whiter, harder finish for distributors who want dependable white coverage without paying premium-brand prices — typically 30-50% cheaper than mainstream European brands.
Features & Advantages
- Bright, True Super White — high whiteness with strong hiding power delivers a clean, opaque white that covers the panel evenly in fewer coats.
- Hard, High-Gloss Film — the two-component cure builds a hard, glossy, full-bodied film with durable color retention.
- Smooth, Even Coating — this acrylic-based liquid coating levels well for a smooth, even finish with minimal orange peel.
- Strong Adhesion & Durability — bonds firmly to prepared substrates and resists weather, UV and daily wear for a long-lasting refinish.
- Easy 2K Application — mix paint : hardener : thinner = 100:50:10-30, then spray 2-3 coats with a 5-10 minute flash-off.

L-688 is supplied in 4L tins. OEM/ODM and private-label packaging are supported; please share your target quantity and destination port and we will confirm the carton packing, price and delivery schedule for your market.
