Resin Paste is extremely helpful for a wide variety of custom projects. The most common is BONDO but there are many variations that vary in ease of use, finishing capability, strength, adhesion and even texture and ability to take stains and finishes. JB Weld is a form of resin paste as it is both an adhesive and a filler. Bondo (and other suppliers) offer resin paste with fiberglass threads imbedded in the paste that creates an extremely strong bond and fill. All are two part materials with the paste and a hardner. When the two are mixed they quickly change characteristics and harden. Once hardened they can be sanded, cut, drilled into and most can be painted or even stained. Some instead of fiberglass have wood fibers and once dry and hardened act very much like wood. (Plastic Wood)
These composites are very versatile and effective at creating shapes and modifying the looks of existing shapes such as stocks, receiver groups etc. In some cases they can save you from buying and then modifying expensive actual parts. There is even material available to make your resin paste look and feel like metal by adding into your mix mettalic dust. This is expensive and omewhat hard to work with but can generate impressive results. I did some Garand Gas Assemblies and had trouble later determining which were real and which were not!
When attaching the filler mix only what you will need and plan on working in layers. Create a channel or use tape dams if gravity will cause the material to flow or drip from your desired shape. Once the mix starts to coagulate stop applying it and throw whats unused out. When applying onto plastic or wood parts I dremel cuts into the pkastic parts or drill holes so the material seaps into the cuts/holes which further strengthens the attachment. If additional strength is needed drill holes and insert some screws leaving them stick out and into the areas you will fill. This will create rebar like interior strength and will make your filler extremely strong and unlikely to break off at your attachment points.
Good luck with this material. Work ith it in a well ventilated area and wear latex gloves. I use wood stir sticks to mix it and stir it up on small pieces of cardboard. I always try to do several mold projects at once so none of my mixed up material goes to waste.
