The lamination line is fine and not under debate from what I understand.
This really has nothing (or little) to do with skill, it may have to do with knowhow, in which case if he doesn't know how to do it he doesn't.
Everything I have posted is based on you having these concernes and bringing them up prior to the job starting and being told it would match. Even with all that said, the job is "acceptable" even though other companies with more experiance laminating may have done a better job. Now only you and your fabricator know exactly what was discussed before hand, but that is what makes or breaks you complaints.
What is your location out of curiosity?
