Opti-bond doesn't need any dwell time as long as there isn't excess product pooling around raised areas and/or impressions on the tire. And you can mix it 50/50 to be sprayed/misted onto the tire
It is very versatile too. Can be used in many of the ways that 303, and other vinyl/rubber protectants can be used, and more. It does actually bond to the surface it is applied to, and last for weeks before most people will notice a major change in appearance, and need to reapply it. I have mixed it with DP tire gel to get a wetter look that leaves a more significant coating on tires, and last for weeks with a glossy shine.
Haven't used any Meg's tire dressings, but the car wash down the road uses a Meg's product that they mixed 50/50 with water, and it slings horribly, leaving the tire greasy. I think the one guy I spoke with about it said it was Meg's hyper IIRC, probably a commercial version that comes highly concentrated.
