I've just read an article about using a liquid plastic product that electricians use to coat wires . The author would paint this on the inside of the scope ring and mount the scope. The material would cure and remain flexible. This apparently acts the same as the synthetic inserts on Burris Zee rings. Supposedly this improved how the scope stayed in place and could compensate for minor alignmenet problems. I was wondering if anyone had any experience with this or similar methods.

The material was made by 3M and is used to paint over wires and act as a pastic insulation.
 
Filler

The article did not indicate this. The author noted that the plastic would fill any imperfections. For example if the rings only contacted the scope on the edges leaving a slight gap on one side. Also, any excess squirted out and was easily removed.
 
You can also use Plasti-Dip, it will not really compensate for alignment problems but it does help the rings hold the scope. It is used a lot for mounting scopes on heavy recoiling rifles.
It is best to lap the rings first to take out any high spots and then put a light coat on the rings, mount the scope and tighten the rings slowly to allow the excess material to squeeze out.
 
The Burris inserts are not flexible after installation. I would prefer using epoxy if I was planning on bedding a scope in the rings.

I want that interface as rigid as possible as any wiggling will cause POA shifts and possibly scope damage.

If the rings have such poor contact, get better rings, or lap then bed the scope. If the cause is an out of whack receiver, get a set of Burris Zee rings with inserts and problem solved.
