Hi Everyone,
I was genuinely curious about something, how late can you apply a topper like Gtechniq EXO? I know usually you apply a topper at the time of a ceramic coating, but I had a friend ask me if you could apply EXO a year or so later after a ceramic was put on (Gtechniq, CarPro etc). I know EXO states that you have 12-24 hours to apply to a ceramic, which is what I do, but I was curious if you could apply it later to an already treated car as long as you do a full wash and panel wipe/eraser or if you are kind of doomed and can only apply at the time of doing a ceramic? I am pretty sure the answer is no, or at best "do so at your own risk", but I wanted to see what you all thought.
Edit: I was curious if EXO can only be topped on a 9h ceramic or if it can be applied to a lighter coating like CQuartz UK?
Thanks,
Sean
