I made it at Techshop
Step 1: Prepare the parts
Once your parts are together, you can clean them up using a scotchbrite pad. This will rough up the surface a little bit and the paint will stick better. It will also remove any wax or other reside on the parts.
To hold the parts while painting, I like to glue them to some balsa sticks. For these I used a 3/16" square stick. I used a little CA adhesive and kicker to glue the balsa stick to the insides of the cowls. CA doesn't stick well to styrene so the sticks will break off very easily when your done painting.
Right before painting, wipe the parts off with a paper towl and acetone.
