OK, here are some pictures of various shotguns and an air rifle, ammo cans, an insulated coffee mug, and the small Royal Ice Chest.
The two shotguns are a .410 Mossberg pump (originally totally black), and a Pardner H&R 12 gauge single shot. Next two pics are of a Gamo Bone Hunter .117 air rifle, full rifle and close up showing optics. Then come various pictures of ammo cans, coffee mug, and ice chest.
Concerning methodology, no matter what item you start with, KT uses brake fluid or acetone to thoroughly clean any oil, grease from the surface....if present the paint will not adhere properly. In the case of the .410, there was some rusty small pitting on the barrel and receiver so it was first 0000 steel wooled, cleaned, and then primed with a gray rustkiller primer. The base coat is camo sand or camo khaki..applied as two light coats to prevent running...long guns are hung for the base coat. Once dry...in about 20 minutes....for leafy patterns, KT likes to spray a few stripes at angles across the gun...first of army green, then of dark earth brown and finally of dark green. Use paints labeled as camo...from Walmart. Then using various plants as patterns, lay them on the gun and spray a complimentary color over it. Practice with the plant on a piece of cardboard to see the effect before hand. When finished let dry, and hit it with 2 light coats of matte clear. This hardens the surface, making the finished product more scratch resistant.
With the 12 gauge, KT followed the same basic procedure, but took pine needles (green ones) and made a thin brush of them about 3 inches wide to spray through...made several of them, for different colors. Spray grass pattern through the needle brushes until you get the desired effect. At the end, spray just a little matte black sparingly in spots for a more dimensional shadow effect. Again coated with matte clear.
For the Gamo air rifle, it was green and black to start with, so KT just sprayed the whole thing flat black, then took some small art sponges, dipped them in spots of paint I sprayed on cardboard, and randomly spotted them around on the stock. Filled in with other paints until the effect was what KT wanted...a leaf litter pattern. Several different paints...when KT looks out one of the Castle windows, the first thing about the woods He sees is light and dark, sunlight patches and dark areas, either leaves or shadow areas. That is the effect KT was looking for!
Two of the ammo cans simply show a grassy pattern...the effect of using the pine needle brushes, one has a couple of spots that started out as a pseudo-snake skin pattern, but ended up looking like 2 fire ant mounds!


The other ammo can shows where I used a small foam brush to dab on twig looking structures, and then sponges to fill in leaves, etc. At the bottom of that pattern, KT used dark woods brown and a trace of black to put in some grass looking structure.
The ice chest used the same method as the .410 and the coffee mug used pine needle brushes. Note the black effect is at the bottom of the mug pattern only.
Anyway, that's the basic procedure and effects on display. KT has two friends who have seen this work and want His Majesty to paint their guns...one being a 10 gauge turkey gun and the other being a very old, very loose unfireable 12 gauge. No charge at this time for His Majesty is still learning and needs items to practice with! HA HA
