Jim,
Red is the tougher not blue. Red can be removed with heat.

My gunsmith friend only puts it on the screw and it doesn't take much.

Don't make the mistake I did years ago, put so much it dripped into the action of a ruger 10/22 and prevented it from functioning! Boy did I feel stupid.

PS I looked for you at Vegas and guys at the LeFever both told me I was always a few steps behind you.
