I am going to remove my old wood railing that encloses my front porch
area.

I am going to install vinyl.

How can I install brass house numbers on the vinyl posts?

If I nail them on, could I split the vinyl? If I glue them on,
what type of glue should I use that will also allow me to remove the
house numbers at some stage when they deteriorate and need to be replaced?

Many thanks.

Kate
