Regular, or fast cure? Right now, Amazon is really letting me down with their shipping, so I may just have another week to wait for regular 5200 to cure. The neighbor has some "stainless steel epoxy putty" coming from his son-in-law who works at a foundry, but I don't think that'll stick to the fiberglass at all. I got some
Loctite Repair Putty since it cures white, but I also bought some epoxy at the same time so I'm sorted for whichever way I decide to go. Gonna test a pinch of the Loctite stuff since it'll be testable in an hour.
What I thought were my weld nuts turned out to be a shipping mistake by Amazon. They instead sent me a 6-flute 13.5mm chucking reamer. The universe is telling me to try the screws first, and fall back to the bolts later. The weld nuts (as well as adding additional screws) were an idea from
@Frank Marshall from this post in this thread about the same issues. Seems like the threads stripping out will happen to me as well. Screws are smaller than the 1/4"x20 bolts I will need, so this will work for this weekend, at the very least. Clearance hole for my screws is already 3/16", and IIRC, there's plenty of room to open them up to accomodate the bolts. The gasket idea was from
@gmtech16450yz from this post in this thread, although I wanted something more substantial than the speed nuts that he used.
@HangOutdoors here's a pic of the weld nuts. I would run the bolts through a washer, through the holes drilled in the cleanout tray, through the deck, and into the weld nut. The weld nut would have some 5200 on the red spot, either front side or back side, depending on how the nut looks when I get it..
Hold the weld nut in place, tighten everything up, and the bolt would hold the weld nut to the underside of the decking while the 5200 cures. There looks to be a "collar" of some sort around the bolt hole, and I would probably use some vaseline or something on the bolt just in case some 5200 oozed over to the bolt. When cured, I'd have 24 individual spots to run the bolts through, and provide some slight pressure to compress the gasket to the deck, similar to
@2kwik4u and his aluminum plate idea to keep the whole area tight to the deck.
