Dodo Juice's first quick detailer is, technically speaking, a spray sealant. This means it offers far higher levels of gloss, beading and protection than a typical water-based QD. Use it on its own if you don't have time to wax the car (just wipe it on and wipe it off... there's no curing time) or add it to an existing finish... it works well over any cured sealant or wax, adding extra 'wetness', boosting slickness and increasing durability.
Red Mist Tropical is the slower drying version of Red Mist. It has the same active ingredients as the original protection detailer, but its slower drying formula gives higher workability and less chance of smearing - especially in hot climates. If you find that Red Mist dries too quickly or doesn't spread as far as you want it to, then go Tropical. It is also less likely to react with underlying layers of wax or sealant, due to the milder solvent, and has a more pleasant fragrance.I am not currently stocking Dodo Red Mist Protection Detailer Spray Sealant as I feel that the Tropical version is a much better value for money.
