So over the weekend I clayed, polished, and applied Optimum Gloss Coat on my new car. Super easy to apply, much different experience than wax or sealants as you don't buff it off, just run a mf light over it to smooth out rough spots. My car is fairly small(porsche 911), I only used 5cc of product. I have 15cc's left over, is it okay to store that for a month or so and then do another car, or do I need to do it sooner? Also, now that's it applied do I need to do anything as it's curing or just not get it wet for a few days? I bought some Optimum qd, is that the best to use to freshen up the OGC after future washings?
