No worries on the :argue mikenap but I appreciate your wanting to make sure.
The problems, and maybe I oughta put that in scare-quotes, are two-fold:
1) Pseudo-holograms, which are sometimes *VERY* minor. I could remove ~90% of them and have it look *perfect* even under the SunGun in a dark shop, and I do mean perfect. But, Accumulatorette and I are both utterly fanatical about anything resembling holograms and in just the right (natural) sunlight, with a certain combo of viewing and illumination angles, and two people who are *really* good at spotting such stuff (one person moves between the sun and the panels to affect a "partial shade to full-sun transition" while the other person also moves to spot that "transitioning rainbow-shadow" affect)...well, they were still there in places.
IPA was only somewhat effective and my old version of PrepWash wasn't much better (the new stuff works pretty well), so this took *ages* to sort out 100% and we had to work at a certain time of day/sun position, so it took a few different days, hence my tendency to rant on the subject. (Props to my wife for helping out!)
2) Similar, but different effects when the M205 is followed by something like ZAIO; a *very* minor, barely visible residue from where the ZAIO seemed to "bring the residual oils up to the surface to get mixed with the ZAIO residue" (or at least that's how it seemed). Said residue was a bear to buff away, but at least re-ZAIOing was usually effective.
This one only happened once, but that was on the beater-Tahoe so it was a lot of territory to clear up. At least I could spot this problem under both incandescents and the SunGun.
Again, both these issues were so minor that I can easily imagine most people never seeing them even after a good inspection. And maybe some glaze/LSP/whatever would sort it out OK :nixweiss
While those are the only "problems", they also make me a little nervous about trying to apply a potentially finicky LSP without a very thorough stripping. Not that I've ever really thought/worried about doing that.
