Sendero,
I've been using bow tape on my stainless rifles for a long time now and it has been great for me.
At the beginning of hunting season and just before my final sight in I tape up the barrels and scopes (my hunting stocks are camo) and at the end of season I just peel off the tape and spray some WD-40 to melt away the remaining glue. You can just wipe it off then.
This solution is really great for several reasons. It's very cheap, easily removed and doesn't affect the resale value of the gun or parts.
It also has ZERO glare because it's cloth tape and you can leave ragged ends of tape exposed for that die cut effect. Just don't lean it against a tree and step away from it... You may end up wasting valuable hunting time looking for your rifle.
In my experience paint chips, peels, and is hard to remove and usually you'll want to remove it one day and rue the day you ever put it on.
