Hey Scott,
Great meetin you at Mojam!!
60 grit is better, I use 50
On the riser, I just bake it, cut and grind to shape and put it back in with the bow, I'm guessin if you have pressure on it in the bow form, it won't go anywhere. No failures doing it this way .
On the overlays, you can just let the EA-40 set for 24 hours , or use CA. EA-40 blends better when you sand, but CA is really fast.
I use CA on any I'm keepin, the one I sent with you is glued with it I'm sure.
Rereadin this, I shoulda just said "What JSWEKA said!!" LOL
