Marine-Tex'able Repairs

1st crack at fiberglassing. I've been following po-man's fiberglass thread/adventure and wanted to throw some pics up to see if Marine-Tex will work for these repairs. The previous patches seem solid, should I grind these back to see what's underneath? Thanks for the advice.
