New Way Firecat 4 Build, Part 12, Masking The Fins

As suggested in the instructions -
One side of fins 1 and 3 are red, one side of fins 2 and 4 are black.

It sounds simple but it's not an easy mask. Trying to get a straight line around the edges of the fin is tough.

I went the easy route, alternating red, white, black and white fins. It'll still capture the feel of the face card picture.

Using strips of Scotch tape (marked with a Sharpie before cutting into strips) the fin was outlined.
Going around the rounded leading and trailing edges requires five small pieces of tape set at angles.

The bulk of the rocket will be covered with a plastic grocery bag.
To get the right size slit over the fin, the bag was pulled and stretched over the outside edge of the fin.

The stretched plastic was cut off with scissors. This allowed the bag to be slipped over the fin and taped next to the Scotch tape mask.



Here's the masking tape holding the bag edge down to the outside of the Scotch tape edge.
The black fin on the opposite side got the same treatment.
