Laminate Cabinets and ASCP

I've had these hideous cabinets
in my "Master" bathroom
since we moved into our house
11 years ago

But they are actually c. 1971,
when the house was built
considering their age
and the fact that they are
crappy laminate
they've held up pretty well...

One day, about 9 years ago, we got creative
and did a tile mosaic on the countertop
I can't say that I love it...
but I know this whole unit is coming out,
and an antique dresser is going in
with a vessel sink

so I had this great idea...
How would Chalk Paint hold up
on laminate?
and not just ANY laminate
OLD laminate
IN A BATHROOM

My bathroom is mostly shades of cafe au lait
also known, in less creative circles
as tan...dark tan, light tan, creamy tan
you get the idea

This PB shower curtain is really the only color
so I mixed up a custom color to bring out the blue..
it's a lovely color

and I might even repaint the
eventual dresser replacement
in the same shade
(maybe I should have written down what I mixed!)

Anyway, it goes against everything I know
not to sand these, prime then, and seal them with poly
but I need to know how it will hold up
with a family using them daily

wish me luck!
The paint is drying as I type...
two coats...wax is up next!
