As red sled said if your paint is already fading or peeling it’s too late . Ceramic is great especially if you do it befor paint accumulates scratches and such .a lot of prep work plus you have to use the right kind c quartz is trusted there are others . There is also graphine coatings now that are really competitive . Two things I recently did mine took 5 hours of light prep work since paint was in great condition you have to remove all prior waxes sealants such than no imperfections or it will look like 💩 second it will have to sit and not get wet for at least 24 I waited 48 hours for the coating to cure one last thing the towels and applicator you used will have to be thrown away since when coating cures it leaves behind shards of glass in them but sealants waxes are good plus chemical guys makes hyrdrocharge which is right on par
