Let me say: Hi and...:welcome:...to AGO!
How to use these pictured products:
-I'm not familiar with these particular products...But:
It sounds like the jobber already gave you directions for these products usage.
As far as needing other products to complete a detail job:
-Are you the one that's going to be doing the vehicles' pre-detail check-list
to determine the totality of the detail job?
-Are the detail-jobs exterior only...or the entire vehicle?
-Are you the owner of this Detailing Business?
This may seem archaic:
It usually depends a lot upon whom you work for...
But I discovered that unless I was the "Boss" of the operations;
and, as long as I felt that my life/health was not being endangered:
It was best suited, for the longevity of my being employed, to follow orders from my superior.
