when I was at that stage I was using the Permashield. I had some leaks at the landing gear/ fitting and I switched to EZ Turn. Sold at all the aircraft supply shops. Permashield separates in the tube and I don't like having thin liquids pour out before the paste comes out. EZ Turn is homogenous. I also benefitted from the tacky tecture from it. Use it to get a washer to stick to a nut so that you can get the nut installed onto the bolt in tight spaces like rudder mount spaces.
