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.
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.

L-688 — hard, high-gloss super white for professional automotive refinishing.
Q: Is L-688 a 2K two-component paint, and how do I mix and apply it?
A: Yes, L-688 is a two-component acrylic system. Mix paint : hardener : thinner at 100:50:10-30, spread 2-3 even coats with about 5-10 minutes flash-off at 23 C, and it cures to a hard, high-gloss white film with a pot life of around 8 hours.
Q: Which hardener and thinner should I use with L-688?
A: Choose the hardener by shop temperature: MK-12X below 18 C, MK-32X for 18-24 C, MK-52X for 25-30 C and MK-62X above 30 C, and match MK-600/601/602/603 thinner to the same range so the film dries and levels correctly.
Q: How is L-688 different from a standard 2K super white, and where is it used?
A: L-688 keeps the 2K super white concept but uses a different formulation and raw materials for a whiter, harder and longer-lasting finish. It suits spot repair, panel respray and full-body repainting of white vehicles.
