This is similar to a question I asked recently about constant QD use over
SG. The answers I got was that there is no reason to put down more SG if it is still protecting. Although it is hard to determine what "protecting" entails. Beading water for example is one indicator but that in itself may not tell the whole story. I think it is a good idea to
AIO and SG once every six months, no matter how much wax you put on or, in my case, quick detailers.
In my case, I keep the truck in the garage every night and it is not driven much anyway. I seem to be always putting on things like
Menzerna's HGAS, FK425 and other top quality QDs. The truck always looks good and never stays dirty. But in harsher climates than mine where things like salt, sand and constant use driving take their toll, it is even more important to clean the paint and seal it on a periodic basis anyway. In this case, I would consider the wax to be more decorative than as a lsp protection step.
