In the wing root fairing thread, there was some discussion of whether rivnuts or ClickBond nutplates were a better choice of fastener to use.
I'm curious to hear a more detailed discussion of why folks prefer one over the other when installing wing root fairings. I would also be interested in hearing why one might choose one over the other for different applications.
Here are some specific questions:
For surface-mounted (no holes required) ClickBond nutplates, how do you ensure precise fastener location when mounting them?
Are surface-mounted CB nutplates suitable for use on curved surfaces?
Would a surface-mounted ClickBond nutplate be an option for the wing root fairing? (Seems like it would interfere with the flush-mount of the fairing, so a through-hole nutplate would be required.)
If you have to drill a hole and use the back-mounted ClickBond nutplates to install the wing root fairings, that requires removing interior trim and increases the installation time. Is there something about the CB nutplate that makes that extra effort worthwhile over a rivnut? (Are you figuring you need to remove the interior trim anyway, to ensure you're not drilling through a fuel line or power cable?)
Seems like if you could ensure you weren't about to drill through something important, a rivnut would be the preferred choice for blind-mount applications. What are the drawbacks to using rivnuts? (Are they hard to install correctly to ensure they don't spin, or can they loosen over time, or something?)
Seems like ClickBond nutplates in general require more time and effort (surface prep, special adhesive, curing time). Backside access is required for through-skin fasteners, and surface-mount parts would be hard to use in applications where precise location is critical. What benefit do the ClickBonds offer over rivnuts to overcome those drawbacks?
