I just got a brand new 2019 honda which has soft paint (Dark grey). I have clayed it. Should I use menzerna 3800 polish and then a sealant or an AIO like Blackfire one step or meguiars 3 in 1 wax. I do not see any swirls or marring on the paint. I guess I am wondering if I really need to use a separate polish first (like menzerna 3800) on soft paint which looks in perfect condition, or will an AIO suffice?
