Chris, there are some 3M automotive adhesive products that are amazing!

In the aftermarket industry, they have been using them to literally glue parts to cars. A company we work with has had a zero failure rate in this regard. Customers who install their own parts may not accept this method psychologically, which is mainly why nuts and bolts are still offered.

Some products will release with a careful application of heat. I don't know enough to recommend a specific product, you may want to investigate further.
