How long does that mix of products last for you? What kind of maintenance do you do in between? Used a buffer to apply?Took about half a day. The Jet Seal has to sit for about 30 minutes and then the Black Light Hybrid Radiant Finish Color Enhancer sits for another 15-20 minutes. So, between washing and hand waxing it's quite the good half day project. Nothing a six pack can't fix.
