Madcow Bomarc Build, Part 2, Parts Prep

I usually dress up the parts before construction.
This involves squaring up the edges and filling nose cone seams.

The burnt edges of the laser cut fins (wings) were squared up with 220 grit on a sanding block.
Most laser cut parts are cut at a slight angle. The laser cut line on top is narrow, the bottom of the cut is slightly wider.
Hold and square the pieces at a 90 degree angle. When you have pieces that will butt up against and glue to other pieces a squared side is important.




The body tube had a slight uneven cut. This is seen on many kits, most builders won't even notice it. Thicker body tubes are harder to cut and should be checked.
Sand and square up if needed by using a block with 220 grit.



After sanding the raised nose cone molding seam, I tried two different methods to fill the concave areas.
I've been wanting to try the Squadron Putty on a plastic nose cone seam.

The upper half got a raised bead of medium CA, the lower half got the Squadron Putty.
On this plastic the Squadron putty didn't adhere as well.
You can see the darkened area where the CA glue was sanded down.
The plastic in this nose cone requires roughing up and a coat of primer for the final color coats to stick.
