HELLO TOM! QUICK QUESTION: I was wondering if it would be appropriate to use a Ryobi cat corner sander to scuff the monokote, or if you think it would be too heavy and gouge the monokote. is sanding by hand the better option. I just thought I would be sanding both the fiberglass fuse and wing tips and the monokote over sheet balsa on the wings. any thoughts here? thanks orion....
