I found all three of them at Big Lots for $2.99 each and tried them out as well. My biggest issue was trying to reduce brake dust on my painted aluminum wheels. I carefully masked one half of both front wheels, apllied two coats of the brake dust repellant and drove around for a week - no noticeable difference in dust rejection. Another week later when I cleaned the wheels, hoping a straight blast from the hose might clear the treated side, but no difference. I'm hoping that it will keep brake dust from gluing itself on or pitting, so I use it about once per month.
The wheel cleaner seems to work the best when applied to dry, cool wheels, I found that I use it with every wash and the dust comes off with a quick wipe. Definitely mild, I can leave it on for 5 minutes and not worry about etching. Haven't tried it on any nasty baked on wheels, so I can't comment there.
The tire shine is not very shiny, sometimes that's the look I'm going for and reach for it first. It seems to soak into the rubber and last for a while, relatively matte finish.
