Gawd, I hope that is true, because there is absolutely zero reason to screw into that hull for something like mounting electronics. I have adhesives in my shop that are something like 7500 Lbs/SqIn strength. Just mount a screw block anywhere you want of any material you want (I'd use structural foam), then screw into that, and it'll be as secure as you want.
