With many removals and installations of the cowl, the mounting holes will be
chewed up and elongated over time. Hysoling stainless tinnerman washers to the cowl after final fit (but prior
to painting) would prevent that. Has anyone ever tried it? The question is
whether Hysol will stick to the back of the washers. Would wirebrushing
stainless washers enhance the ability of Hysol to stick to them?
Yep Sonic,
We did just that on our cowling. Roughing up the back side of the tinnermans
with a sander helped. I can't imagine that the cowling would still function
without them since the screws have been in and out hundreds of times. The body
work was done after they were hysoled in, they don't show at all but still
provide good structure for the machine screws.

[Pardon me for sticking in my 2c here, but if you want those tinnermans (or clik-bond nutplates, for that matter) to really hang in there, don't use Hysol or the Clik-bond glue... get yourself some JB-Weld and use that. I've found that it's adhesive strength when bonding metal parts to a composite substrate to be far superior using the same surface prep (sand/mc). I don't know why this is, but personal experience sure bears it out. Try it, I think you'll like it. <Marv> ]
