DuraCoat is a hard polymer thats self lubricating to a certain extent; extremely hard, oil, solvent, and wear resistant. It resists 100 inch pounds of direct impact and 80 inch pounds of reverse impact. Its pencil hardness runs H to 2H. DuraCoat has passed a 300 hr salt spray test, which far exceeds military requirements for firearms finishes. Major manufacturers such as DSA utilize DuraCoat finishes on their rifles. DuraCoat has proven to hold up extremely well under field conditions. Even on parts such as bolts, which are subject to significant abrasion as the bolt cycles, DuraCoat has held up well and proven to be extremely durable.  DuraCoat will dry to the touch in 20 min and can be used after curing 6 - 8 hrs. However it will continue to cure for 4 to 6 weeks after application. DuraCoat is not a flash cure application. Flash cure coatings will become brittle after curing resulting in chipping and flaking. DuraCoat cures slowly so it remains flexible after it cures which contributes to its excellent abrasion and wear resistance. We like to say DuraCoat doesn't wear out, it wears in. DuraCoat can be applied over just about any surface including, metal, plastic, or wood as long as the surface is properly prepared.
