The rear stud pulled out of my A5 and I know McMillan will fix it if I send it in. I just hate to send it off for something so minor. My best guess would be to use Marine-tex to fix it. Any thoughts on this would be appreciated.
if you can, blow out the hole so there won't be any fiberglass powder floating around loose in there. Then, like previously stated, fill that hole with marine tex/devcon and tighten her down again to the stock. Wipe the excess bedding material that comes squirting out, let it cure, and you've installed the rear stud just like we do here at the shop.
why not just epoxy it in there for good? I dont think that that putting epoxy is going to make any difference, think about it after continous threading in and out the epoxy will start to break and crack thus starting the problem all over again.
