I applied the z1 then z5 and waited about 12 hrs before I removed them. After buffing I noticed some small spots that were removable if I buffed really hard. I then used the gloss enhancer and it removed the spots easily.Is this a common deal? I also did 2 dawn car washes and the clay bar first.Any advice would help as I plan another z5 coat tonight. /phpBB/images/smiles/icon_biggrin.gif /phpBB/images/smiles/icon_biggrin.gif
