Good question....
...I have used regular furniture spray wax, lemon oil, orange glow, walnut oil, .. but it still looks a little weak. The issue is that the existing real teak trim makes the fake teak laminated areas look, well, uh, fake! I don't think there is a product out there that can change that disparity. What I see on newer production boats is real teak trim with fabric or poly covered panels. I have contemplated covering my laminated bulkhead panels with the same material used on the liner, then refininishing the table and galley countertop with a high quality veneer/formica trimmed with teak moulding. The Cetol solution might be promising, but I'm afraid it can't mask the fundamental quality of the laminate. Give it a try in a hidden area. Whatever you do I would be interested in seeing the result.
