Ever have a local drive fail on you? I keep two copies now because losing files once was enough.

No way your pieces fit right the first time.

lol sandra203 you're overthinking this way too much

Holy crap, Dave basically had to become a marine biologist and a materials scientist just to fix a balcony! Chipping through fossilized salt crusts, watching rain attack like it's personal, inventing homemade gaskets in his garage. That's not a repair job, that's a whole survival reality show. They should have just given him an honorary engineering degree and a medal made of silicone.

Check the marks close up before you trust them. I look for faded paint or dirt built up on the line. Takes two minutes and saved my butt more than once.
