I am going to duracoat my rifle this weekend. I have loktite on my base screws its the red. What will I have to do to get them to break loose without stripping, or should I just duracoat with it on it?
I had mine coated with the base on, but if you're in a wet/humid enviroment it might be better to get coating under it. Like hink said heat, 300 degrees if I recall correctly, try holding a soldering iron to the heads, make sure you have a tight fitting bit for the screws, you do not want to strip the heads, if they do not come fairly easy they're not hot enough.
Just leave base on and have at it with duracoat. Red Locktite is some good stuff espically if you were generous with it when installing screws. Throw a allen on it and give it a little force and that will let you know how hard its going to be to remove. Best of luck.
If you don't want to coat it with the base on use a soldering iron held on the head of the screw for a couple of minutes to heat it up, no need to heat the whole receiver.
