I think there are 3 categories now (maybe more) for detail sprays:
1. Drying aid - I think
PB S&W or DP's Rinseless are probably best suited for LSP's in great shape and do not want LSP realy affected
2. Drying aids with some added gloss/slick - lots to choose from based upon preference (smell, ease of use, slickness, etc)
3, Gloss/Slickness/Protection on clean surface (during or after drying) - spray waxes
