Rick, I dip three tines full strength with a gasket, then rub down with the brown abrasive pads. I then crest, optionally of course, then shellac over the crest and dip twice or three more times,then rub down with 0000 or the gray abrasive pads and fletch with Duco.
Target burn means less than nothing to me. Yes it is a wee bit soft but no so bad if it goes on in thin coats.
I spray my feathers with MHSU in a can for a totally waterproof arrow! (not to much or they will turn into stiff vanes)
