OPI Gelcolor users... do you use all the steps?

[wendynailart]

I've read many who use Gelcolor say they do not buff the nail (says to on the OPI instruction page) prior to application and have great results
Made me happy, I prefer to not change the nail surface of clients committed to natural nail

OPI also recommends NAS and Bondaid prior to application
I've used them both (trial run) to improved adhesion, they seem to have dried the nail out a lot

Q is.... those who are using Gelcolor successfully, do you do all the steps?
if you alter them, what do you do instead?

Thank you for saving me the trial and error that sometimes turns a client off a new product ;-)
