Eric, I was referring to stainless fasteners. I remember hearing horror stories from mechanics who didn't want to work sheet stainless. Although for the Chrysler Building, too damn bad.

I know it's sheet metal and all but not historically accurate, at least not before 1929. Plus I know lots of guys who hate workin it. Personally I like it but one of 'em said, "man made stainless, god made copper." Rest assured you don't want "that" attitude on a stainless project.

Eastern Standard Time, [log in to unmask] writes: We've done several cornice restorations and heartily shy away from the use of fiberglass cladding, a material that is very susceptible to UV deterioration. So why aren't the fiberglass boats falling apart? Huh? well? Because the owners are smart enough to haul them onto the hard and paint them before they need it. Those who don't suffer the consequences with failing gel coats and delaminating hulls. Will have to check this with my friend the former yachtsperson. But I never heard of anybody having trouble with fiberglass boat hulls. Why? Because the likelihood that any cornice is going to receive the required attention and be repainted on a cyclical basis is very slim And who's going to paint the galvanized? The same guy, but unlike fiberglass the galvanized or other sheet metal won't fall apart in five years if it's not painted. I wouldn't hold my breath. and metal, even galvanized, is going to be more durable than piece o'shit plastic. Yeah, but the fiberglass at least has some thickness built into it, which the micron-thick metal isn't going to have, especially where it's been stamped damn near through in order to get a decent profile Fabrication stamping is much more controllable than it was 80 years ago, and you can always refuse defective thin section pieces. So you go through every square millimeter of your cornices (or other metal stampings) with a thickness gauge, do you? Most of the failures that we've seen are principally related to fastener corrosion - So use stainless fer Chrissakes. We do now; they didn't then SO we'll take that outta the equation, too. Jeez, Louise. a result of inadequate metals separation and subsequent galvanic corrosion, and water infiltration into the cornice because no one wants to perform proper maintenance. So the maintenance is a wash either way. In that case, take it outta the equation. Also the crappy appearance of 3/4" sealant joints between pieces of plastic on cornices makes me want to puke. Yeah, well, the pukey appearance of the joints makes me want to crap, but it's less apparent on higher buildings. How's your eyesight these days, gramps? I stopped when I needed bifocals. They don't make them tall enough not to notice.You must step in lots of dogshit looking up at cornice caulk joints. Remind me not to take a job as your bootblack. Fiberglass =lower cost up front, big cost up the wazoo later. I can't argue it isn't a pick your poison sort of thing, and will admit the uniformity of color in some of the fiberglass leaves a certain amount to be desired.
