This great tip was shared by cerecdoctors.com member Dr. Eric Hosek:
This is an easy way to sandblast the TiBase without waxing, blocking out, or other more time consuming methods. I used the rubber tip protector from a Filtek compule to cover and protect the connection. You need to make sure you slide it over the widest part of the platform about 0.5mm or it will pop off. I do not have it pushed on far enough in this picture. Quick and easy!
