Estes Mini Arcas, #2441, Part 17, Pulling The Tape!

The mask was pretty clean, 

There was some small bleeds under the corners.

Instead of scraping - 

Try pushing the little paint overspray tics back into the red. 

I use a pocket knife, it's not as sharp as a hobby knife. Too sharp a knife might cut in and chip out the white paint underneath.

Here's the cleanup results up until now.

I'll follow with some white touchups. 

Ace Premium enamel is sprayed into a cup and applied with a brush. Applied light and carefully, the Ace paint mixes and "melds" into the paint already on the model.
