Very nice build, looks you have achieved the shape of hull very perfectly.
Use PVA (at least two coats) with sponge. You can dilute the PVA with water if required.
Later on you can use wax while copying from moulder i.e.(fiberglass to fiberglass)

You must always try to achieve maximum finish job before applying putty, not too dependent on putty to cover up.
Yes automobile filler are very hard to sand, use NC putty / Asian putty those are used by carpenter and every steel almirah units. easy to sand with water.
