What washing/drying techniques and other advice to you guys have to prevent swirls? I just did a complete polish on my car and a coat of AIO and SG so I want to keep it nice. I also want to add another layer of SG, being that it's been 2 weeks since my last application. I just washed my car using the Eurow sheepskin mitt and microtex microfiber drying towel from walmart, and it worked great. However, when I but my car under the halogens, I noticed there is still some water residue that the microfiber left behind, not exactly spots, but just residue from the tiny droplets of water it left behind. Is it okay if I went over it SG??? Anyone have any answers? Thanks.
