[PSUBS-MAILIST] Viewport retaining bolts

Title: Viewport retaining bolts

I'm building viewport seats for flat disc viewports like the ones in a K-350 coning tower. But I'm wondering about a little detail that folks surely have some practical advice on. The acrylic is to be retained by a screwed-down ring. With that arrangement, how do you avoid rust in the bolt threads? (my seats are not SS). I'm thinking I could use studs with nuts instead of bolts, though it wouldn't look nice. Or I could get fancy and use O rings to keep the threads dry. But everyone else seems to use ordinary SS bolts and I haven't seen rust streaks coming from them. How d'you manage that, are you just gooping the threads up with some sealant?

Thanks,

Alec
