West Systems epoxy makes an excellent pinhole filler. I know this by actual experience. After you have done your fiberglass lay up, there is always the pinhole issue to deal with. The simple solution is to mix up a batch (does not take much) of West and using a plastic putty spreader, coat the area of pin holes to be filled. West epoxy is thin enough where it will run in and fill the pin holes and not just cover them. When doing this method, be sure to squeegee off all excess. The West will completely dry and not leave a sticky surface even with humidity in the air. DO NOT try this method of pinhole filling with any other epoxy because you will wind up with a sticky surface. I personally used Aeropoxy entirely throughout my aircraft and used the West as a pinhole filler only.
