Guz, Ron, thanks for the quick replies.
I'm starting to understand some of the differences in each Optimum product better. As in many brands, there seems to be quite a bit of overlap between products. While I understand how this creates syngery it makes it harder for me to determine which products are must-haves to make Gloss-Coat work best and which ones are beneficial, but not mandatory. But I'm slowly figuring it out.
To that end, does using ONR, or Optimum Car Wash or Opti Seal or Optimum QD make Gloss-Coat "last longer"? Given your comments about Gloss-Coat shedding or not allowing other products to stick, I would guess no. It seems like all of these, in reality, are only temporary in the way they affect the surface. And while these are obviously part of the "system" and great products on their own, they don't affect the Gloss-Coat performance. I hope I got this right.
In fact, while perhaps not recommended, it seems I "could" use Z6 as a QD to get rid of some dust on the paint. Since the effects of Z6 will only be temporary anyway. Same for using any shampoo, I assume. Don't grimace, I'm thinking I will get the Optimum equivalents but was wondering if my assumption was correct.
I have started watching some Rag Co. videos and will look into it more, thanks. But since you brought up Opti-Seal, that's a product I don't really understand well. It's main purpose is for protection, but it doesn't last long on Gloss-Coat. So was it mainly developed for those who want protection but don't have Gloss-Coat or Opti-Coat? Guz, you do mention using it as a possible drying aid, but beyond that I'm not sure where it fits into the scheme of things.
Thanks for holding my hand, guys. I'm getting there!
