Dyna Tek bore coat, Dyna bore coat, UBC (ultra bore coat) - same difference.
From the manufacturer ...
Dyna-Bore Coat Service, Dyna-Bore Coat used to be known as Ultra-Bore Coat. Same Manufacture, Same Formula, New Name, New Packaging
One tip when applying "UBC"
is use a bore mop cut down to a ball. A full length mop soaks up and wastes more than what's needed to give a thorough coating.
