Rocketarium Hydra Sandhawk Build Part 21, Fin Attachment Pieces

The instructions give you two choices to make a double layer of card stock for the fin mounting attachments.
I simply glued the back and folded over the card. I dried flat in a book.
You could cut out sixteen pieces then glue and stack them. Folding, gluing and cutting seemed easier.

I set the double thickness card stock piece next to the root edge to mark the gold area for paint removal.
A smaller area than the attachment piece was scraped away down to the body tube.

Each fin attachment piece was pressed against the Sharpie barrel to put a slight curve in it.
This will better fit the curvature off the body tube.

The fin attachment pieces were attached with white glue.
There is no paint on the upper stage fin attachment pieces, they are white on the finished model. I might "seal" the faces of the pieces with some white glue applied with a Q-tip.

Gluing the attachment pieces on after the gold paint is applied gives a sharp color separation, better than you might get by complex masking.
