Lubegard Power Steering Flush and Protect, does it work?

[BufordTJustice]

I use Redline D4 ATF (Dex III) in my Lexus GX460. Mix that with the correct treat rate of Lubegard PS Protectant and the steering is literally better than new (directly compared recently to my new, 2200 mile loaner GX460 during service).

Never used the flush.
