preventing ring marks on your scope ?

I believe I had read in a post about putting electrical tape on the rings ? Can anyone confirm this ?
 
I use painters tape on my rings and eliminate marks on scopes. I have also used Burris rings with inserts which also eliminate marks. If you already have rings that you like, use tape.

I torque my rings to the base with a lapping bar installed in the rings. It helps keep things well aligned during tightening process.
YUP,. THEN, I'd LOOSEN the rings and,.. put some Lapping Compound on, the round Bar for, a few light, "Strokes", back and forth ! Then, Clean off Lap compound, degrease and Loctite, screws, & Bore Sight ! Did this a Bazillion times, back in the Day ( 70's 80's, mid 90's ),.. when I was, a GunSmith with, Happy, customers for, only, $35 Bucks !
Still "works" great ( with, NO Ring marks ) to this Day !

If you need to stop Ring marks, this works every time for me.
Elmers Rubber cement is what I use. Other brands may work also.
Liberally coat both ring halves. When you mount the scope the glue is going to push out all around the scope and really look bad. Don't touch it for several hrs. When the glue has cured, it very easy to peel of what
you can see. The part that's under the bottom of the rings can be removed with a cloth. Just pretend you are buffing polish of the toe of your shoe. No ring marks and the scope wont slip. I use this on any ring brand that's not a Burris Signature. LDS
 
Poor quality rings are mostly the culprit for ring marks,... or way over tightened out of alignment rings. I have even found some top quality rings with burrs on the edges which if left alone would "dig in" to the finish.
Now Sightron scopes have the softest finish I have ever found on a scope and those will leave "imprints" in the finish every time, for me.
 
Rebs. You just have to pay attention to placing the incerts in the rings evenly before tightening the ring screws. It really should not need saying but I read on the forums where people have trouble with them.
 
The biggest cause by far is guys over tightening the rings. I can't understand someone paying $500+ for a scope but too cheap to use a torque wrench to properly tighten the rings. If you want to do it right, use the alignment bars to ensure concentric alignment, then bed the scope in the rings (or use a little tape), tighten only to recommended torque, and I guarantee you won't have marks on the scope.
 
There are several moving parts to this. Its wishful thinking that the rifle receiver, scope base and scope rings will result in a perfectly aligned scope. Add in a military receiver that's been milled, drilled and tapped and you have lots of miss-alignment issues. I've started glass bedding the bases on my sporterized mauser rifles. Best practice is to buy those pointed aluminum alignment bars to get front and rear rings aligned as close as possible. That's assuming you're using Leupold, Burris, Redfield style 90 degree dovetail style mounts. Then use a ring lapping bar and polishing or valve grinding compound to take off the sharp edges of the bottom rings. I have not figured out how to lap vertically split rings like Talley.
 
The compound that I got with my lapping tool is used up. Is there a source, other than Sinclair, for this? I believe it is water based.
