From what I've read on the site, DS is for very light cleaning and BSW is more for a shine on top of that or a wax. If I'm on the wrong track, please let me know
From Steve@Adams:
"When it comes to everyday wipe down to remove dust, finger print smudges, and add shine to wax, look to our Detail Spray. It contains no wax or cleaner so it's perfectly safe to use on glass and paint in direct sunlight! Streak free and great smelling, you'll end up using it by the gallon full! Use it between waxes to maintain the polymers in our waxes.
Our Brilliant Spray Glaze is more of a "show glaze" that can be applied weekly to add even more shine than our wax could by itself. It's applied much like a coat of wax but has no protective properties - its earned its claim to fame by making paint, glass, chrome and stainless steel look amazingly shiny and get car show judges looking your way!"
