Tbh if that's the case then I would look to go with my last suggestion dodo juice lime prime and a White hex logic pad as this will give you a vast improvement over what you can achieve by hand. It will increase the clarity of the paint, mask and fill the majority of imperfections (depending on how deep of course), then apply your sealant and wax.
You do not necessarily have to apply both a sealant and wax and the view of some on here is that it's a waste, however personally it's all down to how much time you have, over night storage of the car and weather conditions.
Generally in the summer/warmer months you do not need both. What are you currently using as protection?
