Curiously Recurring Template Pattern and statics in the base class

Question

So thanks to this answer I'm looking at implementing my problem with CRTP. However I have a problem. In my static base class I have 2 sets of functions. One takes std::vectors and one takes a standard C-style array. So in the base class I define a static function that calls the non-std::vector function.

However when I derive from that base class I seem to no longer be able to access the public static function in the base class (Which I thought I could).

template< class Derived > class Base
{
public:
    static void Func( std::vector< float >& buffer )
    {
       Func( &buffer.front(), buffer.size() );
    }

    static void Func( float* pBuffer, int size )
    {
        Derived::Func( pBuffer, size );
    }
};

I then define the derived class as follows:

class Derived : public Base< Derived >
{
public:
    static void Func( float* pBuffer, int size )
    {
        // Do stuff
    }
};

However when I try to call the static function in the Base class:

Derived::Func( stlVec );

From the Derived class it throws a compilation error:

error C2665: 'main' : none of the 2 overloads could convert all the argument types
1>          c:\development\Base.h(706): could be 'void Func( float*, int )

I assumed that I would be able to call a public static defined in the base class from the Derived class. This appears not to be the case, however ... Can anyone suggest a workaround that doesn't mean having to implement the std::vector function in every one of my Derived classes?

Func in the derived class hides all base members with the same name. Use using declarative to bring the names from the base class into the derived class.

class Derived : public Base< Derived >
{
public:

    using Base<Derived>::Func;

     //rest..
};
