Meguiar’s No. 7 Show Car Glaze or Meguiar's No. 3 Machine Polish??
 

Has anyone used either or both of these and which one do you prefer best. I have a PC and will be using that ot apply this so I'm guessing #3 would be better suited for me but I want to see what your experiences are with these.

I use the No. 7 Show car glaze, it leaves a nice texture to the paint. Almost like a prewax, and it adds a nice shine to it.

Number 7 does a great job in bringing out a deep wet look to the paint. You should use a paint cleaner before number 7 and follow up with a wax.

Meguiars Color X is great to use before No. 7.
