If you are talking "Meucci" style I can't help you - that is far beyond what I can understand w.r.t putting clear over a fantastic leather grip. However - if you talk about products to prevent dirt build up and a good shine, I would recommend you to contact Tiger Products..
Of all the wraps I have installed I have never put clear on any of them, but Tiger Products have good stuff which should help you out to keep the job "safe" from dirt, chalk, sweat - for quite some time. Then mention to the end customer that the grip should be treated like a good pair of shoes!!! If not, take it back for a refinnish and charge him for it - thats what I do
