New Way Letter - Go Build, Part 11, Tube End Masking

I like to keep paint out of the tube ends. Paint can slow a smooth slide of an engine into the engine mount and a nose cone in the top of the body tube.

I rollup a piece of paper towel.

A painting wand is slid into the engine mount.

The paper towel is pushed into the recess below the centering ring.

Cut off the paper towel overlap and press in the end.

I use tweezers to get the paper towel into all the open areas.

On the open upper end with the nose cone removed - 

Some masking tape is rolled around the end of the tube.

Before pressing the tape in the tube,

Press the sticky side of the tape on your pant leg and pull off. This leaves some lint on the tape making it less sticky.
