always have had excellent results with detail spray:
after a waterless wash i use 3 towels ( two single and 1 double) top down, panel by panel 1 shot of DS on the towel two shots on the panel changes sides of towel on each panel. Change to second towel when needed. Final wipe down with double soft towel.
after 2 bucket wash i do the same method swap in the drying towel for the single soft towels.
by priming both the towel and the panel you lower the chance of introducing swirls
