Estes Thor Agena B Build Part 36 Fillet Bubbles!

After the first white color coats had dried I found bubbles down the tunnel joints!
I though the fit of the tunnels was good enough that fillet bubbles wouldn't be a problem.
After two fillet coats of white glue, they were everywhere.

I didn't want to use to use the beige CWF. That'd mean sanding, more primer and then more white coats - too much added weight.

If the bubble filler was white, it would simply mean sanding the white filler and then just a white overcoat.

This is the Hobbico Hobbylite filler I used. It's an old container, I had to mix in some water to get it to a workable consistency.
Some have said it's the same white wall spackle you find at home improvement stores. Pick up the containers and compare the weight, buy the lightest one.

It's pretty easy to press the filler into the joints with the side of a razor blade.

Try and remove as much as you can while it is wet. This stuff dries hard but is pretty easy to sand with 400 grit.
