Yes, I see that the five hours spent in the hot garage addled my brain somewhat and weft y'all with some questions.
Since 2012 BMW was perfect upon receiving last Decenmber, all I've had to do is Optimum No Rinse Wash and use Optimum Instant Detail Spray for the most every few days. More for the practice than the need, I did clay it once, and use Optimim Poli-Seal to clean it up a but, IPA'd and use Opti-Coat. A couple of Optimum Spray Car wax apps and it always is in near perfect condition condition for me.
So this made me unestimate the work needs on the daughter's old and neglected 2000 Mustang. It was in the oppossite starting condition. A few dents, some rust showing through, cracked paint, RIDS galore. It was neglected when she bought it five years ago and hasn't been touched since is my guess and with some dents, RIDS and rust it was in rough shape.
Yes, I did wash it and clay it the best I could. First thing I noticed is I needed some wheel cleaner and maybe IronX which I haven't needed for the BMW.
And Flash Gordonn was correct that reversed my MEguiars' products. I actually did first apply the 105 Ultra-cut flowing the clay THEN the 205 to try to finish it. At least I hope so I'm pretty sure I DID right but DESCRIBED it wrong. My apologies for reversing them in my text. My arms were too tired from three passes around with the Porters (but thank god it wasn't being done by hand!).
I don't know if it was the procedure and slowness that allowed the 105 to dry so hard that MF's couldn't budge or if I should have known a better way such as IPA, of using the PORters with a bonnet or other trick to try and remove more residue before trying to finish too early, I hate to finish too early (that's what she said!).
Having the Ulimate Paste Wax seemed to have saved the day and was able to clean through all the residue and leave it in an acceptable condition after all.
I knew detailing her car would not be as easy as mine but I should have done a bit more research beforehand for procedures and a couple more products like the aforementionedfor wheels as well as a ragtop cleaner/dresser. So I'm trying to learn a couple more tricks before I do such volunteer work again as my son's Suburu might be next. Wanting to expand my "subjects" beyond my easy BMW before i go "pro" after retirement from my day job.
I did a quick scan of The Art of Detailing and only mid-step step that jumped at me was perhaps the wipedown with IPA but not sure if that would have worked through the dried 105 residue or not. Hence the questions to the more experienced.
