Estes Great Goblin, #9724 Build, Part 22, Masking Off The Body

A slit was cut in a plastic grocery bag. 

This was slipped over the soon to be black fin.

Masking tape is set over the Scotch Tape strips and onto the plastic bag.

Another plastic bag was cut and wrapped around the upper end of the body tube leaving only the one fin exposed.

Before spraying I lightly sanded the orange peel a bit. This is your last chance at a final sanding. Don't go too deep, just knock off the tops.
