Well,  POR-15 is extremely hard - and it'll surely survive those rock chips.
But - its biggest advantage - of bonding to the steel, keeping moisture out,
stopping rust & moisture from traveling between paint & steel, etc - require
that it be painted directly on the steel.

You *can* paint it over existing paint.  But, you loose all advantages
except its hardness.

I'd consider it quite cheap - compared to almost anything else.  It costs
less than half the cost of a quality underseal, durabak, etc.

It can be painted or sprayed.  But, since it has a lot of isocyanides (sp?),
I wouldn't spray it without much better respiratory equipment than I intend
to buy.  So, I've brushed it on in the past, and will be brushing it again
in a couple of weeks.

Their website, www.por-15.com, has quite a bit of info; and their online
sales folks are terrific.  They were able to give me info about temperature,
product compatability, etc, etc.

I'm going to be using POR-15 on the interior, and 3M underseal on the
bottom.  The underseal product comes in a handy aerosol can, I've seen it
last over 10 years, tends to fill minor gaps, etc.
