My targa seals are good... I remove it occasionally for nice highway cruises, and it goes back in leak-free... assuming I tighten it properly. My rear hatch seal is another discussion...
Poodles, is the order that critical: dri/s front than pass/s front? I do the two rears good and tight, then whichever front is closest to snug, then the other front to snug, then snug up the rear, then snug down the fronts alternatively, in no particular order. I figured doing one bolt straight to tight, one at a time, wouldn't let the targa sit properly.
