Welcome. I use primarily Wolfgang and Durlagloss products as well. I'm lucky enough to have the makers of Duragloss, Brothers Research, right here in my hometown of Burlington, NC. Known those guys for several years.
What kind of car will you be using these products on? Your process should be:
Wash
Clay
Wash
TSR with orange pad
FG with white pad
DGPS with blue pad or by hand (2 coats with 12+ hours between coats)
