I have tried lots fo waxes. Liquid and paste Meguiars Gold Class (still got half a tin of it) Liquid and paste Meguiars #26 (got a tin of #26 and a gallon of #26) Blitz Wax (half a tin left), Pinnacle Paste Glaz, Pinnacle Souveran (4/5 left), and maybe another bottle or can of wax somewhere that I forgot about.
My opinions
Meguiars #26 in paste form is easy to use, maybe just as easy as Blitz minus the white stain on certain trim pieces. Blitz wins in the durability department, apply every 2-3 months. But for #26 paste apply thin coats every month to month and a half. The resulting finish is nice and feels slick, good wax for the money, also available locally at Autozone at $10 a can.
For speed and ease of application, finishing pad and PC for Meguiars #26 liquid. It lays down a thin even coat that removes easily. A little faster than by hand becuase I just squirt a few drops onto every other panel and just go around spreading the #26 with the Pc.
Meguiars GC paste has around a 3 week durability. Its shine is very similar to Souveran, but doesn't laste quit as long and may haze on certain german finishes (BMW or MB.) I found the paste to actually dull and make the silver BMW more of a stain color, the #26 cleared this up after a dawn wash, and Klasse + Blitz blew me away.
Meguiars GC liquid is like the paste but I only used it once.
So in closing, #26 if you plan to polish/glaze often or top off a polymer sealant such as Meguiars #20 or Klasse. Wax once a month.
Meguiars GC if you like to wax often.
All (liquid or paste) are fairly easy to remove, harder than Pinnacle, but easier than 3M or Meguiars polishes.
