Basically,

They have you using a piece of sandpaper folded over a thin metal ruler to clear the cloth and resin from hinge-line on top. As I'm looking at the obechi, I imagine I'm going to need a lot of filler to get rid of the wood grain?

Also, anyone used Robart robostruts in these gear instead of the Duro-struts? A set of three of the Robart costs the same as one main strut on the Duro. Are they that much better?
