UPDATE:
Well, I put on a coat of the prime and the trigger (P/T) before the car went into the shop last week. Here's my take on them:
1. Prime: directions say to leave it on 30 minutes to haze. Unlike AIO, which is WO/WO, the prime is "supposed" to dry and then be wiped off. The directions recommend letting it dry for at least 30 minutes. Unfortunately, once the prime is dried, this of course takes "elbow grease" to remove. This is the only thing I don't like about it. When the car gets back from paint, I'll try the WO/WO method and see if there's a difference. The durability seems to be better than the AIO/SG combo, as it rained a few days after I put the P/T on and rained for about 4 days. The car still looked very glossy, even though dirty, and the rain beaded very well.
2. Trigger: directions also say to allow to haze, but this fortunately takes only a few seconds to do. The trigger comes off much easier than the prime does, and I would say that the overall protection and ease of use is better than the Klasse SG.
3. Price: price comparison between the two gives P/T the slight edge over the AIO/SG. The P/T is only available in one size though atm while AIO/SG can be had in many sizes.
4. Appearance: I give the edge in appearance to the P/T combo over the AIO/SG combo. The P/T seemed to look more glossy, even though I hadn't applied a coat of Natty's Blue over the P/T like I usually do with the AIO/SG. In fact, I'd say that the appearance of the P/T w/o the carnuba top coat matched the AIO/SG's appearance WITH the carnuba top coat. It looks very nice on the black.
Overall I wouldn't hesistate to recommend this combo to anyone who wants to dry something new and very good, while being affordable at the same time.
