[QUOTE="Bart B, post: 98216, member: 5302"] I've used MarineTex with great results. It's popular with several match rifle builders. Devcon Plastic Steel is also great. Years ago I did some tests with two flat steel surfaces held against two 1/8th inch ground pins. After applying release agent (Simonize car wax, rubbed very thin) to both surfaces, I filled the gap with a popular epoxy bedding agent, When they cured, I took 'em out and measured how thick the 1/8th inch thick pieces of cured epoxy were to determine how much they shrunk. Results are listed below; least shrinkage first: 1. Devcon Plastic Steel tied with MarineTex; less than .001 inch. 2. Bisonite, a bit over .001 inch. 3. Accraglas and one other brownish colored stuff I forget its name; a bit over .002-inch. [/QUOTE]
