Back last fall I detailed my car for the first time, and used #7 and S100 wax. The second time around, I was disappointed at how dull it looked, and bought S100 SEPC. When I detailed the car using it, it looked utterly fantastic. Since then, I've detailed my car only once (few days ago... simply washed my car through winter, didn't have time or energy to polish and wax too...takes me awhile since I'm still kind of inexperienced), and it sort of seems that it isn't as deep/wet looking as it was the first time I used it...it might be that I was just so surprised and amazed the first time, but in any case, I still have a bottle of #7 lying virtually unused, and wondered if it would help at all. I figure I may as well experiment and use both, but I don't know which order would be best...#7 is a glaze, so I would assume that I would use the SEPC first and then the glaze, and then the S100 wax. If so, how long would I have to wait after the SEPC to use the #7? And could #7 actually muddy the paint up and make things look worse (dull)? Thanks.
