Would it be ok to use the water blocks and rads after flushing with distilled water and then add this whole bottle of corrosion blocker with distilled water?

I don't want to mess this up, any help would be great!!
Corrosion is only a problem when you are using aluminum in a loop with copper/brass. That crap you got with the rad is just under 70% ethylene glycol. On top of the "nasty stuff" in the link, it also hurts thermal transfer to the water due to a much lower thermal capacity.
