In repairing cracks in gel coating I removed them with a 1/4" ball mill chucked in a hobby tool (dremel). I do not recommend a die grinder as it is too aggressive and the slightest pressure will cut through the fiberglass. Just remove the gel coat and not the fiberglass! On this boat the whole job took less than two hours.
Blow out the dust and wipe with a solvent such as acetone or mek. Take caution with these products. They are highly flammable!
Fill areas with tiger hair. It is a long fiber filler by Evercoat. Sand and glaze with 3M glazing. This product is water proof it is easy to sand...it does shrink and may need more than one application.
