Estes Mk-109 Stingray Build Part 6 Fin Prep

There is a mold line running around the outside of the fins.
This will show up when paint is applied so you should sand it down and re-round the edges.

Some of the TTW fin tab have rough edges from when the fins were broken off the molding trees.

These should also be sanded off. With that plastic nub on the root edge the fin won't seat all the way into the notch.
