"zebra"Most people fill their cf bottles on their rifle at home. It is their scuba or scba tank that you take to the paintball or dive shop for a fill.
The main reason not to hydro dip anything on your gun is that you might want to sell it some day. You would limit potential buyers to people with your taste. Personally, I would never buy an air gun that someone has covered in camo paint etc. I think it looks hideous but that's my taste. I like to keep my guns in factory condition.
There is no reason it would damage your bottle as long as the valve was sealed. After all they are made to be air tight. Maybe keep it off the threads though...
I agree about resell. I like my guns camouflaged since I am into hunting more than shooting or collecting. Probably not even that big of an edge, but I guess it is kind of physiological . Power positive thinking if I think it helps, it does. I also agree they are not really things of beauty, after the treatment. But it sound like other than that if is ok. I will be doing it in a few weeks if I can get my ducks in a row.
I only hunt with my air rifles, I never really target shoot or plink and while I would never camo my Cricket, I am curious to know how much it makes a difference. At the distances I shoot from, the squirrels don't seem to notice me unless I make a noise or move too much. If I shoot and miss, they often make incorrect assumptions about where the danger is coming from and run towards me instead of away. I tend to shoot down from a higher position than them so the pellet hits the ground behind them. For this reason, I'm fairly sure they generally can't see where the danger is coming from.
My guess would be that animals are more likely to spot something that is unnaturally reflective than my black on black rifle. Nothing in nature is as reflective as man-made coatings except water. Some of those dips looks fairly glossy in the pics.
I believe that some of the dips are designed to be removable so you could get the best of both worlds from your perspective.
I don't think a non glossy wood stock is much of a problem, but I do think black is very noticeable. I know a black Bear is huge, but when we encounter one in the woods we can see him a mile away, even through trees. the black color really stand out. they may be shiny , but even other black colors are not really a natural or normal color you see in the woods where I hunt. If I am in woods where I am not going to encounter OP, then I cover my self up pretty good in camo, even my face.
