B -- only for rush blooms eh....
So do you use only A , followed by clay as a strong prewash/prep prior to polish ? |
I think of the "A" as just a super-shampoo. It will supposedly neutralize any acidic contamination (acid rain artifacts) but that's never been a *huge* concern of mine...nice that it does it, but not my primary reason for reaching for the product.
Being the Acidic step, the "B" is the stuff that "burns out" any ferrous contamination and thus solves/prevents rust-bloom issues; no iron stuck in your paint, no iron there to rust.
Here's a example of only using the "A": Many used Audis have compromised (clear anodized) aluminum trim, something I do *NOT* want to expose to anything acidic (acids getting into any breaches in the anodizing will "cloud" the aluminum, permanently). So while I'll use the "A" (or maybe the equivalent FK stuff, I have some of that on the shelf for the next Audi project) to really, and I do mean *REALLY*, clean everything off for a "clean slate" starting point, that's the only part of the decontamination system I'd ever recommend for a used Audi unless there are specific rust-bloom issues.
If a used Audi *did* have rust blooms, then yeah, I'd use the "B" on it, but man-oh-man would I be careful about keeping it off the aluminum trim pieces. But if no rust-blooms, then I figure "why bother".
