Masking reflection

[Shine]

For a bit of background information, I'm a 3ds max convert, and loving XSI so far.
I'm currently texturing an setting up materials for some metal and rubber parts.
The nice and shiny new metal should looked scratched and worn, so here's what I need to do.

I'd like to mask the reflection, so there is no reflection visible in the areas where the map is painted black. Also, In those areas the material should have a high specular value.
I'd also like to modify the diffuse value in those areas too.

The second thing I would like to achieve is to create a shader with 2 speculars, as if something had been painted with a varnish.

I'm not yet familiar with XSI materials and shaders, so some help here would be much appreciated.
Thanks

just paint the different maps and plug them in, its pretty simple.
I can't find the link to the tutorial I had,

but its as simple as making the reflection map,
hit ctrl 7 in xsi,
find the material you want to add the map to,
node > texture > image >,
edit the image and import yours,
then drag the red dot to the phong or whatever it is,
and click on whatever type of map it is under the list.
