I have heard great things about both of those products, especially the Colinite. Yes, if and when you get a coating(carbon or silica based) both of those products will then hinder more than help. If you get an Si02 based coating(CQuartz and Ceramic Pro for ex.) Reload or similar SiO2 based sealants are your go to. If carbon based(Chemical Guys or AMMO) then you will need different maintenance sprays.
Fun stuff! Depends how deep you want to get into it. Some have claimed I am over thinking the coating care process and products. But, when dealing with such an investment, sorry but I'm going to do exactly what the products says I have to. If it says avoid fillers and gloss enhancers, I AM!
CQuartz is what I am thinking so reload is the ticket. I just haven't tried it on uncoated paint yet.
