Duracoat Aerosol Firearm Finish Kit (Magpul Dark Earth) Same great DuraCoat now in an Aerosol Can! ***NOTE - DuraCoat in AEROSOL is NOT a true FLAT finish. The aerosol chemicals add a sheen to the finish that appears more "satin" or "semi-gloss." If you want a true matte finish order the DuraCoat in the 4 oz bottle. Spray it with an airbrush, or pick up a Preval Sprayer at any Home Depot for about $5. It will spray on a true FLAT with no sheen. Aerosol Kit includes a 12 oz can of DuraCoat in a 2-part "can-within- a-can" delivery method, a 6 oz can of TruStrip cleaner/degreaser and a special scrub pad. Enough DuraCoat for 1-4 firearms depending on coats and thickness. No baking or preheating required
