Today I've been cleaning up the Chinese Type 53 (Mosin M44 analog) that I got off Gunbroker last week. I noticed a crack in the handguard that seemed to have been glued back together, as soon as I started heating it up to get the cosmoline sweated out the glue failed and it split back into two pieces. The temp was around 100 degrees, which seems pretty low for glue failure to me. I have some epoxy, but it starts to soften a bit above 100 degrees, so I'd like to use something with a higher temp rating. Any ideas?
