OK, over the weekend I used Meg's SMR on my car, then a Dawn wash. Yesterday I put a coat of Z1 & Z5 on there, using my PC and a Meg's soft buff pad (their softest one). I follwed the directions from here and Z's home page by lightly spritzing the pad with Z6 prior to putting the Z1 on the car. Occasionally, there would be spots of Z6 and I'd wipe them up, but I wasn't able to get all of them. Now it doesn't look like they will come up. So will a Z7 wash take care of it, or am I going to have to "spot treat" with SMR/alcohol and then re-Z1/Z5? It really irritated me to see this, since I spent so much time on the car to get it looking as perfect as I possibly could. Thanks for any info!
