dear safdar bhai
a long ago i used whole 3 step process on my 2004 silver civic
mother claim it "pure polish" and its first step to prepare the base for further 2 steps, as its polish so its remove swirls, secratches , oxidation, old bulidups of wax layers, usualy polishes smoothen the paint, give deep clear gloss but what i remmber my experince with this polish was something differnt, yes its remove the old buildups, oxidation but prominent the skin imperfactions like secratches and dull the skin 
i belive there must be something wrong with my application at that time as mother is renowned brand.
however step 2 micro polishing glaze enhance the vission in paint and deep gloss
after step 3 i noticed my metalic silver more clean , clear with more metal flake pop but many of light secratches still there ( for which i firm belive its due to my inappropriate application and lack of thorough massage of step 1)
this 3 step is good product but its life very short until u seal it with sealant
in case if u use this 3 step system than my rout map wuld be
step 1 - step 2 - syn wax- step 3
i belive syn wax before step 3 would enhance life
