Some of you have heard my biggies before, but anyhow:
-Burned clear with PC/4" Polishing/3M05937 of all combos! Only time I`ve ever done that to a paintjob in the 40-some years I`ve been buffing cars.
-Overthinned the paint on a few, including the `93 Audi (very different from "burning" the clear). Yeah I have an ETG, no I don`t really have any excuses other than (and I`m serious) I`d rather have risked/lived with the resulting paint damage than still see the marring I could`ve left...every time I`ve done this it was an informed judgement call; my game/my rules. Upside was that I`ve found that exposed pearl/base/primer coats can actually hold up, and even protect, quite well for many years.
-Using the steamer, I`ve melted the plastic retaining clip for a hood-prop rod, the carpet in two vehicles, and the doorpanel fabric one one. Still don`t get the carpet damage since the exact same procedure worked fine on all the surrounding areas of the same carpet.
-I`ve ASSUMED that a final light wipedown with FK425 wouldn`t mess with recently applied Collinite 476S. Wrong...had to strip/redo a car that had been ready to go.
-I`ve botched the layering of FK1000P and had to deal with the resultant pseudo-holograms.
-I`ve left holograms, of some degree, on every b/c car I`ve ever rotaried. ALWAYS cleared `em up with a RO/DA, but still...I just never got 100% dialed-in with regard to finishing out hologram-free, finally quit caring.
-I`ve chipped paint with the metal fittings on a hose because I dropped it instead of setting it down carefully.
-I`ve marred paint by not replacing the QD that attaches the Foamgun to the hose soon enough (popped off under pressure).
-I`ve marred paint by allowing the uncushioned edge of a work platform to hit the vehicle when I bumped into it (upside: discovered that many layers of KSG can provide an amazingly effective barrier/sacrificial coating that can minimize such damage, lucky me!)
-I`ve marred paint during the wash by not retesting my Wash Media frequently enough.
Eh, I must be missing something (and if anybody here remembers any OOPS! I`ve posted about, please mention it)....that`s an incredibly (as in "just not credible") short list for a guy who started in the mid-70s and I`m sure I`ve botched up more stuff than that, but nothing else is coming to mind. I *am* awfully careful about what I`m doing and quite dedicated with regard to thinking stuff through before/during/after any procedures. Even now I`ll think on something like my Maintenance Wash Regimen for extended periods on a regular basis, filling pages with notes/thoughts. And I maintain a very good focus on the task at hand, don`t even have the tunes on any more lest I be distracted. As with almost everything else in life, virtually all of my mistakes could`ve/would`ve/should`ve been avoided by more, or better, thinking.. so I keep working on that.
