[QUOTE="Darryle, post: 2656354, member: 109917"] I use painters tape to prevent squeeze out from getting into magazine wells, barrel channel and on the sides of the stock. I use some form of epoxy adhesive a couple of times a day, preparation is 90% of the work. We use different types of release agents. The 2 most common agents we use [URL='https://www.freemansupply.com/products/accessories/semi-permanent-mold-release-systems-solvent-based/semi-permanent-solvent-based-mold-release-agents/chemlease-mono-coat-e150-n-ods-semi-permanent-release-agent']Mono-Coat 150[/URL] [URL='https://www.henkel-adhesives.com/us/en/product/mold-release-agents/loctite_frekote_44nc.html']FreKote 44[/URL] These are probably cost prohibitive for most people. Before applying a release agent I generally heat the substrate up, whatever I want to apply the coating to, apply liberal amounts of release agent, allow to flash off, apply a second coat, allow to flash and repeat until I have thoroughly coated anything I don't want to stick. We use Meguiar's Ultimate Paste Wax in some instances, depends on the substrate, especially if it is coated/painted. I use a modified version of my regular routine, just at a lower temperature. You can do the same thing with most any quality paste wax, it's just harder to get into the small cracks, recesses and crevices without heat and sometimes it's impossible even with heat, so a liquid works best. I have long thought about making reusable fillers for rifle actions and this product was what led me to think on it more. I use SocoMore moldable shim, we use it at work and it has a shelf life, once expired it has to be disposed of or destroyed. It works great for a variety of projects, like filing cavities that you want to prevent migration of epoxy resins. 😉 The great thing about it is very firm, if you use a quantity of items that are identical, say the same action, you can make one mold and reuse it continually as long as you use release agent on it. It doesn't shrink and is by nature resin resistant. It is sandable as well and very resistant to tearing or chipping. You can make a filler mold a little proud for the magazine cut for example, sand to contour and apply release agent. Pop it in and pop it out when done. We have literally used some of these filler molds thousands of times with various heat cycles under pressure or vacuum on them and they are still in great condition.
