One Clear, Every Repair: The FMB Classic Clear Coat Lineup

Two 4:1 clear coats from Finnish Master by LKQ, built to handle spot, panel, and overall repairs.

Not every job calls for a specialty clear. Sometimes what a shop needs is a dependable, do-it-all clear coat that can flex across job sizes — and that’s exactly the niche Finnish Master by LKQ (FMB) fills with its Classic Clear lineup. Both clears in the lineup mix at a 4:1 ratio and are rated for spot, panel, and full overall repairs, with the main difference coming down to VOC compliance.

FMB 4142 Classic Clear

The FMB 4142 is a 4:1 classic clear coat built around flexibility:

  • Three activator options — fast, medium, or slow — selected based on shop ambient temperature
  • 5–10 minute flash time
  • Bakeable at 140°F for 30 minutes

It’s a straightforward, general-purpose clear for shops that want one product capable of covering spot repairs up through full panel and overall jobs.

FMB 4121 Classic Clear (2.1 VOC)

For shops operating in VOC-regulated markets, FMB offers the 4121, a 2.1 VOC version of the classic clear. It shares the same core profile as the 4142:

  • 4:1 mix ratio
  • Three activator options — fast, medium, or slow
  • 5–10 minute flash time
  • Bakeable at 140°F for 30 minutes

The tradeoff is simple: same performance and workflow, lower VOC content for compliance in tighter-regulated regions.
