So I have this extra TA01 just laying here and decided to sell it. Turns out no one wanted it.  I guess its fate because I decided to go ahead and do a nice camo job on a rifle and might as well spray the Acog to match. So I am going to use KG Gun coat as I have some sitting here. How do I spray and cook the optic without destroying it? I know its tough but how tough? Will the heat at 325 degrees for 1 hour screw something up? Should I bead blast the body first before spraying or just make sure its real clean? TIA |

Boom, I would suggest you do not use a thermal cure on your ACOG, I don't think the results would be good. If you want to try it, and don't mind experimenting, I would ask that you spray it, then cure at 200 degrees for 2 hours instead of the usual higher temp and shorter time. You should end up as much safer doing it this way. While I'm not a duracoat fan, it may be worth using for the optic. Now when can we see pics of that camo job?

Paradude thats a great idea I will do that. Stick your right that temp is high for any scope. I like your idea of 200 for 2 hrs it should have the same effect. Man I hope I don't fxxx this up. But some body's got to do it....  It will take me a week to get it finished. I have several mods I need to make to the rifle and rail I'm using. I'll post pics as soon as its done. Oh! Should I bead blast the scope body first? |
That’s a good suggestion. When I was considering painting my M4gery I took a look at the Testers paints. You definitely get more of a selection of colors. |
I have used them in the past for gun projects and whats cool about the Testors paints is, even though it's not needed for them to dry, that you can put what ever you paint in the oven and really speed up the curing process. I have painted a couple lowers in the past with Testors...it held up well... |
Its easy enough to check to see if the item cured properly when using the lower temperature. After 2 hours, pull the item out of the oven and use some lacquer thinner or acetone to rub a section of the finish. It it starts to come off, its not fully cured. Do NOT bead blast it. Bead blasting dulls a finish, but it does not rough it up enough for a finish to adhere properly. Sandblasting would be fine, but bead blasting would not. I've seen a few recent posts on ARF where people have said to bead blast before applying a finish, and that is not correct info. |

Boom, Dont bake the optic at that high of a temp. Professionally I do not recommend thermally cured coatings be used on optics or electronics. Send a sample of the KG colors that you are doing the rifle in to Lauer Custom weaponry. They can color match some DuraCoat to match the KG colors. DuraCoat dose not need to be baked to cure. It is safe to use the next day but will require 3 to 4 weeks to fully cure. If you have any questions about application give me a call. Joe |
