PBH,
Yes, the Gloss Enhancer is the Zaino Z6 product. It's really great stuff. I use it for touch-ups all the time.
It's a watery liquid that comes in a spritzer bottle. It's nice because there's no residue when you're done.
Of course, with any "touch-up" kind of product it's important not to use it on a dirty or heavily dusty car. In that case you'll need to do a wash. Sometimes my car just has a bit of dust and I'll just rinse off the dust and use the Z6. I do notice that the Z6 helps with the dust.

Z-6 "Gloss Enhancer" spray is a very important addition to the Show Car Polish line-up. This product dramatically boosts and intensifies all Show Car Polishes. Z-6 contains seven optical clarifiers and our unique wet gloss enhancers to increase the "wet-looking", mile-deep Show Car Polish shine. We highly recommend it for fast cleaning of dust, water spots and light soil from painted surfaces, without scratching. Forms a tough molecular bond with Show Car Polish to increase the depth of gloss, optical clarity, slickness, durability and reinforce the UV(40) protection. Super anti-static formula reduces dust and dirt pickup by up to 60%. Z-6 will not streak, smear, haze, dull or leave a film. A must for quick touch-ups and the show winning edge. Concentrated 16 oz. spray. Less than one ounce does an average car.
