Modelcrazy, I used 0.060 inch Evergreen plastic rod for the depth charges. I cut them to relatively long lengths of about a half an inch. I would lay several pieces out flat, parallel to each other, and rolled up against each other. I'd use Tenax to glue the lengths together. Then, I'd cut all the depth charges to length at the same time using a razor blade. I cut them to about 0.100 of an inch.
The paints are mostly AK Interactive. I used AK 5001 for the 20B deck blue, and AK 5004 for the 5N Navy blue. I got these colors in AK's set US Navy Camouflages (AK5000). I'll use Tamiya for the red hull and black book stripe.
I have a few comments about AK interactive paint. I used Vallejo Primer. The AK paint goes on very nicely with the airbrush. However, small chips tend to lift with the more aggressive masking tape. 3M painter's blue tape lifted quite a bit of paint, which resulted in small chips. However, Tamiya masking tape did not lift paint. Brush painting to touch up the chips resulted in a different sheen to the finish. I'm hoping that this difference in finish resolves itself with gloss coats and final dull coats.
