My Way of Demolding
Like others have said, two holes will be left if you remove the rear wing. Not sure but filling them with Bondo and then using touch-up paint might work. Best would be to have them filled buy a good welder and then have whole trunk painted.
I think nothing new, but...
My method for removing the side moldings and side badges: Spray WD-40 (using small diameter red tube nozzle) along top of molding; Take micro-fiber cloth (thin one used to clean eye glass lenses) spray it heavy with WD-40 & wrap it over the "knife" edge of a flexible putty knife (make sure and keep entire edge of putty knife covered with cloth; slide "protected" edge of putty knife under end of molding (I started at car's rear), between adhesive and car's paint, and push/wiggle it along (try and keep molding as flat as possible so it does not bend in case you want to put it back one day). I was left with some adhesive residue & used a thicker micro fiber cloth soaked in WD-40 to scrub and remove. Then I noticed a little ghosting (car was nearly 1-year old). I then washed all the WD-40 off and clay-barred (lots of car wash soap and water in a spray bottle for clay-bar lube) the area where the molding had been. All clean, no problem, no sign that molding had ever been on car, no paint bubbles. Doors look so much bigger. I like the look!
A couple of weeks later (after ordering) I received a box of "Zaino" with lots of their car polishing stuff. Washed, clayed, washed, and then applied their polish. NICE. I haven't taken pictures, but come see the car anytime!
