Ok, i just started zainoing my car for the very first time this morning. Started with a dawn wash, followed by a claying with clay magic clay and Zaino Z-7 mix as a lube. I accidently moved the clay over to a part of my hood that wasn't lubed and the clay came to a screeching halt. I proceded to really get it wet with z-7 followed by more claying and i thought i had removed it but i didn't. it must have been the lighting in my garage because after i put on my first coat of Z-5 and was buffing it off i noticed the smear mark still there. Can anyone tell me what my next step should be to get this stupid mark off my hood? i've tried z-6 with microfiber and its not budging. help!
