I just got my ABC in the mail that I am going to try and use to remove some stubborn water spots that Vinegar and other things haven't touched. My question is, I dawn washed, clayed, SMRed etc to try and get these spots off before. Once I failed, I put a coat of Z5 on just to protect things while I waited for the ABC. Now that the ABC is here, will it remove the Z or do I need to do something else first?
Thanks.
Thanks.
