Yea I have a cover, and I did use it actually because I did the detail over 2 days. It's a California Car Covers "NOAH" cover. 4 layers, breathable, all that jazz...probably the same as yours handz. I just ran out of time the night before the show, thats what I was getting at. My memory is getting bad in my 22 year old "old age" haha. I can't even remember what I did each day, all I remember is I had so much shit to do both days that I didn't start detailing until like 2pm each day which clearly wasn't enough time to get everything done I wanted to. I did the engine bay, interior, wash, and clay the first day, covered it, then did the M105, wash, and E-Zyme wax the second day, then covered overnight and left the next morning at 7am for the show in PA. It was all worth it, the car had some moderate swirls that I couldn't stand any longer and the AM show was an excuse to do the detail.
That E-Zyme is such an amazing LSP!!! I had been using Autoglym HD, then I won the E-Zyme in a CG contest, and I love it so much. Too bad there is no way in hell I'm spending $275 on a tub of wax!
