For those of you who use a spray sealant as a topper over either a ceramic coating or another paint sealant, how often are you reapplying your topper spray sealant? (i.e reload, black fire, etc)
Further, what is the sign to reapply? Is it when you notice the beading reduces significantly during routine washing?
