Honestly after washing the car I'd rather just take an hour and use 50/50.
Unless you've been reading the directions on Ultimate where it tells you to use on the car between washing NO WAY who in their right mind would do that

eguiars Ultimate Quik Detailer is a spray detailer plus a wax booster in one! The Hydrophobic Polymer Technology creates a high level of surface tension that results in a slicker, darker surface that repels water like never before! The slick coating holds up to several car washes and adds another layer of protection over the existing wax or sealant.
If your usual quick detail spray doesn’t last, you have to try Meguiars Ultimate Quik Detailer. It leaves a lasting coat of gloss that reinforces the existing paint protection and deepens the shine. Use it between washes to instantly remove light contamination and restore gloss.
Meguiars Ultimate Quik Detailer is a high lubricity formula that is safe on all types of paint, including clear coats, single stage paint, and ceramic clear coats. The lubricants wrap around dust and dirt particles to prevent scratching. Meguiars Ultimate Quik Detailer can be used every day to remove dust and fingerprints.
Make sure your vehicle is cool to the touch before applying Meguiars Ultimate Quik Detailer. Spray one section at a time. Spread the detailer over the section using a folded Cobra Super Plush Deluxe Microfiber Towel. Flip the towel to a dry side and buff the vehicle dry. Repeat these steps until you’ve detailed the entire vehicle.
After 12 hours of curing, the polymers in Meguiars Ultimate Quik Detailer will achieve their maximum level of protection.
Meguiars Ultimate Quik Detailer can also be applied after each wash to refresh the existing paint protection. You’ll be amazed at how the towel glides over the paint!
