I have been bedding rifles in Acraglas (but not the gel) for fifty years. I dislike the gel because it is degraded by Hoppes#9. This is an unforgivable shortcoming IMO! By the way, the same thing applies to Devcon Steel or EK-10. Great product but Hoppes will degrade them. I have not tested Belzona or Marine-tex with Hoppes. Since 1971, I have used Acraglas, Glasbed, Devcon Steel, JB Weld, Acraglas gel, Bisonite, Belzona, and various other generic epoxies. My first choice is still Acraglas. GD
