You'll end up with a better finish on the outside edges and a stronger glue bond on the root edge.
I like to "seal" the exposed edges with wood glue.
Apply a very narrow glue line down the outside edge you'll be seeing on the finished model.
Smooth the bead using the side of a finger.
Sand the glued edge with 400 grit.
Probably good idea to repeat some of the points you've brought up in earlier blog posts on why sealing edges of the cardstock parts is a good idea. for example:
ReplyDelete* improve appearance -- cardstock edges tend to be rough
* lessens chance the edges will fray/delaminate over time
* reduces chance the part will sell during painting (cardstock edges tend to be porous and apt to swell by absorbing paint - much like unsealed wood).
