Sepia 2 Kosmiczny Kuter

After very busy autumn im back with little bit more time on my hands, and with few fresh ideas.
One of them being the futuristic looking ship- Sepia 2.
It will be complete scratch build, with plenty of weathering.
Hope to show some progress soon.

Probably the best, and easiest way of making the balloon is by cutting the frame of the balloon out of cardboard, and filling the spaces with low expanding builders foam.

I made the balloon frame using 2mm cardboard, and white glue. Cavities were filled using foam. It will prevent the frame from deforming after the expanding foam is used.

I used the lowexpanding poliurethan foam to fill the balloon frame up.

I filled all the major gaps, and holes using the same foam and spatula.
Now i will rest the balloon for few days to cure completely before i use the car filler.

Note the 2 attach points on both ends of the blimp.

Then it was time for the car filler.

I sprayed the dull black, and started covering the blimp in acrylic filler:

Oil canning effect added:

Blimp in primer:

Microfilling with acrylic filler:

Masking tape was used to make rubber seams, and whole blimp was sprayed with floor varnish:

Helium inlet valve added:
