  John van Stelten offers repolishing and coating services.
He isn't cheap but you should ask the actual price.
Repolishing the lens will affect its thickness very
slightly. In general thickness has much less effect on lens
performance than other parameters so its practical. The key
is the depth of the scratches. Very shallow scratches may
only affect the coating.
