colej Jeff the difference is you are doing this as a professional charging for your services. The hobbyist can make changes when needed as it's their clubs. Grips do move whatever G'Buzzers say. One grip moves says a lot about the clubmaker that is offering their skills for a price. Use tape and don't worry.
I use build up if needed and one layer of 2 sided use Brampton's HF-100 Grip Solvent. Light spray on tape, I use light air.
Non-flammable
Non-toxic
Odorless and free of harmful fumes
Effect with all Tapes
I have never had a grip move and no ticked off customers.
