Default Countersink

I countersinked. You can do either but I like the results on the countersink better. Don't go too deep.

I do remember I under bent the longerons in that area and had to do some adjusting. If you don't get a quick response here, PM or hit the Vans Aircraft Facebook page.

I dimpled all four canopy decks and countersunk the longeron. The dimples came out nice and crisp! I even dimpled after paint was applied.
