I've diluted the SG: 1 part SG to 6 parts water, for use as a 'top-up' after washing.
The mixture isn't slick enough to use as a QD, but immediately after washing, there's no dirt to mar the surface. By taking an extra 3-4 minutes to spray/wipe the SG mixture, the protection never runs out. I've gone 2 years or more without reapplying the AIO/SG by using this method.
Eventually, you'll find enough scratching/spider webs/stone chips that you'll want to strip, polish & redo the whole enchilada - but until then why not take the easy way out. . .
