Presoaks Stacked Or Don't Stack

So that pic was taken in April when I was testing a new chemical from Chemquest for my rep.
(which I m not allowed to talk about yet)
I did 27 draw tests that day.
Easy as 123.
That was with lab made product.
This past week I got a regular production run, the first, and did it all again.

I've always run a very strong high and never had any real issues in the Summer with 98% of the cars. I have measure car temps with an IR thermometer and some hoods are 130 degrees. But on painted surfaces I have seen zero issues. There is some anodized trim on certain vehicles that will blush from caustic solutions and I am primarily seeing that now on some Teslas. However, that could be the onboard tire cleaner doing that. But you can literally search "tesla discolored trim" and see it is a widespread issue. It seems that auto engineers don't learn from their mistakes, The problem with anodized trim has come up again and again on various car models(PT cruisers, some Volvo SUVs, and some C-class Mercedes). I think they anodize and then don't cover it with clearcoat. They discover the problem, fix it and then it happens again on another model. I've tried lower alkalinity polymer products such as synergy in an effort to minimize this but they didn't work well in my area.

Since this thread came up I will again say I feel like a dog chasing my tail. Tried chemquest last year and although it worked pretty good it was not the secret sauce for my area. I went back to Quest low/high ( CG 110/210)and it was working great all fall and Winter. Then, Spring came and I started seeing a film again following the warm rains. I pushed the alkalinity up and still no dice. Finally went the other direction by weakening the low about 25% and brought the high back down to where it was before. Now the cars are looking really good overall.

How many ml's of 210/110 were you using in the winter and what did you go down to in the spring?

Thanks
