Does anyone have any ideas how to make the rough, textured look to US Navy bombs? The Navy’s bombs are treated with a texture to prevent them from cook-off in a fire. I have a bunch of 1/48 Hasegawa bombs but they arent textured. Any ideas would be awesome! 
The best method I have found is liquid glue. I use the Testors liquid glue with the brush. I apply a small amount on the bomb casing and when it gets tacky to the touch, run the brush over it again. Do small sections at a time and experiment on an old bomb to get the feel.
Do only the bomb casing, not the tail fin section. The tail section is not textured.
I take mine to work and sand blast them lightly, then I clean them in an ultrasonic cleaner for 10 minutes or so. Outside of that, I have no idea how to get them textured like that.
i’ll try the glue method since i dont have a sand blaster lol. Thanks for the ideas guys!
I’ve used a technique on two occasions which works very well, although it’s a bit more tedious than most other methods. I simply cover the area to be textured with putty, masking off the untextured areas.
While the putty is still malleable I’ll use a slightly cut-down acid-brush to lightly stipple a bit of extra texture in. A plastic stencil or fabric brush (found in most craft stores) will also work for this last bit.
Once it’s dry I then chip off the mass excess and clean up with some light sanding. It takes a bit of work to get good consistent coverage, and a light touch when sanding to avoid smoothing the surface out too much, but I’ve gained much better results with this technique than with any other I’ve tried. For me, the superior results are worth the extra work.
In the end, however, it all comes down to personal preference…
