I would not advise repairing the damage you described with 1 - 1/2 oz mat. If you have compromised the laminate (cracked the hull) you need to re-build with at least an equal strength repair. Grind away on either side, use at least 18 oz fab mat or biaxial cloth and epoxy. For outside repairs, wet out the patches on a tray, hold them in place with some plastic film and dct tape, and let cure. grind smooth, and THEN start in with microlight and the "body work" part of the repair. Got to get some strength before making it look pretty...
